One of the pioneers and authorities in physical chemistry is Gordon M. Barrow. He was a professor of chemistry at Northwestern University for over 40 years. He authored several textbooks on physical chemistry, including his most famous one: Physical Chemistry. This book was first published in 1961 and has been revised and updated several times since then. It is widely used and respected by students and instructors of physical chemistry around the world.
The 6th edition of Barrow's Physical Chemistry was published in 1996 by McGraw-Hill. It is a comprehensive and rigorous introduction to the principles and applications of physical chemistry. It covers all the major topics and subtopics of physical chemistry, such as thermodynamics, quantum mechanics, spectroscopy, statistical mechanics, kinetics, electrochemistry, surface chemistry, solid state chemistry, and nuclear chemistry. It also features many examples, problems, tables, figures, and appendices that illustrate and reinforce the concepts and methods of physical chemistry. The 6th edition also incorporates the latest developments and discoveries in physical chemistry, such as lasers, superconductors, nanomaterials, etc.
In this article, we will give you an overview of the main topics and features of Barrow's Physical Chemistry 6th edition. We will also show you some examples and applications of physical chemistry that demonstrate its importance and relevance for science and society. By the end of this article, you will have a better understanding and appreciation of physical chemistry and Barrow's book.
Thermodynamics
Thermodynamics is the branch of physical chemistry that studies the energy changes and transformations that occur in physical and chemical systems. It also deals with the relationships between energy and other thermodynamic variables, such as temperature, pressure, volume, entropy, etc. Thermodynamics helps us to predict the feasibility and direction of chemical reactions and processes, as well as to calculate their efficiency and spontaneity.
Barrow's Physical Chemistry 6th edition covers thermodynamics in chapters 2 to 7. It starts with an introduction to the basic concepts and laws of thermodynamics, such as the zeroth law, the first law, the second law, and the third law. It then explains how to apply thermodynamics to various types of systems, such as ideal gases, real gases, solutions, phase equilibria, chemical equilibria, electrochemical cells, etc. It also discusses some advanced topics in thermodynamics, such as thermodynamic potentials, Maxwell relations, Legendre transformations, etc.
One of the examples that Barrow uses to illustrate thermodynamics is the Carnot cycle. The Carnot cycle is a theoretical model of a heat engine that operates between two reservoirs at different temperatures. It consists of four reversible processes: isothermal expansion, adiabatic expansion, isothermal compression, and adiabatic compression. The Carnot cycle shows that the maximum efficiency of a heat engine depends only on the temperature difference between the reservoirs. It also shows that no heat engine can convert all the heat into work without violating the second law of thermodynamics.
Quantum Mechanics
Quantum mechanics is the branch of physical chemistry that studies the behavior and properties of matter at the atomic and subatomic level. It also deals with the nature and interactions of light and other forms of electromagnetic radiation. Quantum mechanics reveals that matter and energy have both wave-like and particle-like characteristics. It also shows that physical phenomena are governed by probability and uncertainty rather than determinism.
Barrow's Physical Chemistry 6th edition covers quantum mechanics in chapters 8 to 14. It starts with an introduction to the basic concepts and principles of quantum mechanics, such as the wave-particle duality, the Schrödinger equation, the uncertainty principle, the superposition principle, etc. It then explains how to apply quantum mechanics to various types of systems, such as particles in a box, harmonic oscillators, rigid rotators, hydrogen atoms, multi-electron atoms, molecules, etc. It also discusses some advanced topics in quantum mechanics, such as perturbation theory, variation method, molecular orbital theory, etc.
One of the examples that Barrow uses to illustrate quantum mechanics is the photoelectric effect. The photoelectric effect is the phenomenon of emission of electrons from a metal surface when it is exposed to light of a certain frequency or higher. The photoelectric effect shows that light behaves like a stream of particles called photons rather than a continuous wave. It also shows that the energy of each photon is proportional to its frequency and independent of its intensity. The photoelectric effect was one of the first experiments that confirmed quantum mechanics and challenged classical physics.
Spectroscopy
Spectroscopy is the branch of physical chemistry that studies the interaction of matter and electromagnetic radiation. It also involves the measurement and analysis of spectra, which are the patterns of wavelengths or frequencies emitted or absorbed by matter when it is excited by radiation. Spectroscopy helps us to identify the structure, composition, and properties of matter by analyzing the spectrum of radiation it emits or absorbs. It also enables us to measure physical quantities such as temperature, pressure, concentration, etc. by using spectral lines as reference standards.
Barrow's Physical Chemistry 6th edition covers spectroscopy in chapters 15 to 18. It starts with an introduction to the basic concepts and principles of spectroscopy, such as the electromagnetic spectrum, the selection rules, the intensity and shape of spectral lines, etc. It then explains how to apply spectroscopy to various types of transitions and interactions, such as rotational, vibrational, electronic, nuclear magnetic resonance (NMR), electron spin resonance (ESR), etc. It also discusses some advanced topics in spectroscopy, such as laser spectroscopy, Raman spectroscopy, Fourier transform spectroscopy, etc.
One of the examples that Barrow uses to illustrate spectroscopy is the infrared (IR) spectroscopy of organic molecules. IR spectroscopy is the technique of measuring the absorption of infrared radiation by organic molecules as a function of wavelength or frequency. IR spectroscopy shows that different functional groups in organic molecules have characteristic absorption bands in the IR region. These bands can be used to identify and quantify the functional groups present in a sample of organic matter. IR spectroscopy is widely used in organic chemistry, biochemistry, environmental science, etc.
Statistical Mechanics
Statistical mechanics is the branch of physical chemistry that studies the behavior and properties of matter at the macroscopic level based on the statistical analysis of its microscopic constituents. It also deals with the relationships between thermodynamics and quantum mechanics. Statistical mechanics helps us to explain and predict the thermodynamic properties and phenomena of matter from its molecular structure and interactions.
Barrow's Physical Chemistry 6th edition covers statistical mechanics in chapters 19 to 21. It starts with an introduction to the basic concepts and principles of statistical mechanics, such as the Boltzmann distribution, the partition function, the ensemble average, etc. It then explains how to apply statistical mechanics to various types of systems and processes, such as ideal gases, real gases, chemical equilibria, phase transitions, etc. It also discusses some advanced topics in statistical mechanics, such as quantum statistics, Bose-Einstein condensation, Fermi-Dirac statistics, etc.
One of the examples that Barrow uses to illustrate statistical mechanics is the Maxwell-Boltzmann distribution of molecular speeds. The Maxwell-Boltzmann distribution is the probability distribution of the speeds of molecules in a gas at a given temperature. The Maxwell-Boltzmann distribution shows that most molecules have speeds close to the average speed, but some have much higher or lower speeds. The Maxwell-Boltzmann distribution also shows that the average speed and the spread of speeds depend on the temperature and the mass of the molecules. The Maxwell-Boltzmann distribution is useful for calculating various properties and phenomena of gases, such as pressure, viscosity, diffusion, etc.
Kinetics
Kinetics is the branch of physical chemistry that studies the rates and mechanisms of chemical reactions and processes. It also deals with the factors that affect these rates and mechanisms, such as temperature, pressure, concentration, catalysts, etc. Kinetics helps us to understand and control the speed and direction of chemical reactions and processes, as well as to optimize their efficiency and selectivity.
Barrow's Physical Chemistry 6th edition covers kinetics in chapters 22 to 25. It starts with an introduction to the basic concepts and principles of kinetics, such as the rate law, the rate constant, the order of reaction, the activation energy, etc. It then explains how to apply kinetics to various types of reactions and processes, such as elementary reactions, complex reactions, chain reactions, enzyme-catalyzed reactions, surface reactions, etc. It also discusses some advanced topics in kinetics, such as collision theory, transition state theory, unimolecular reactions, etc.
One of the examples that Barrow uses to illustrate kinetics is the iodine clock reaction. The iodine clock reaction is a classic demonstration of a complex reaction that involves several steps with different rates. The reaction consists of mixing two colorless solutions: one containing potassium iodate (KIO3) and sulfuric acid (H2SO4), and the other containing sodium bisulfite (NaHSO3) and starch. The reaction produces iodine (I2), which reacts with the bisulfite to form iodide (I-). The iodine also reacts with the starch to form a blue-black complex. However, the blue-black color only appears after a certain time, which depends on the initial concentrations of the reactants. The iodine clock reaction shows that the overall rate of a complex reaction is determined by the slowest step in the mechanism, which is called the rate-determining step.
Electrochemistry
Electrochemistry is the branch of physical chemistry that studies the interconversion of chemical and electrical energy. It also deals with the phenomena and processes that occur at the interface of an electrode (a conductor) and an electrolyte (an ionic solution). Electrochemistry helps us to understand and utilize the electrochemical reactions and devices that involve the transfer of electrons between chemical species, such as batteries, fuel cells, corrosion, electroplating, etc.
Barrow's Physical Chemistry 6th edition covers electrochemistry in chapters 26 to 28. It starts with an introduction to the basic concepts and principles of electrochemistry, such as the electrode potential, the Nernst equation, the standard hydrogen electrode, the galvanic cell, etc. It then explains how to apply electrochemistry to various types of electrochemical systems and processes, such as concentration cells, thermodynamic cells, electrolytic cells, electrode kinetics, mass transport, etc. It also discusses some advanced topics in electrochemistry, such as potentiometry, voltammetry, electrochemical impedance spectroscopy, etc.
One of the examples that Barrow uses to illustrate electrochemistry is the lead-acid battery. The lead-acid battery is a common type of rechargeable battery that consists of two electrodes: a lead (Pb) anode and a lead dioxide (PbO2) cathode, immersed in a sulfuric acid (H2SO4) electrolyte. The battery produces electricity by the following redox reactions: Pb + HSO4- PbSO4 + H+ + 2e- (at the anode) PbO2 + HSO4- + 3H+ + 2e- PbSO4 + 2H2O (at the cathode) The overall reaction is: Pb + PbO2 + 2HSO4- + 2H+ 2PbSO4 + 2H2O The lead-acid battery shows that the electrode potential and the cell voltage depend on the concentration of the electrolyte and the state of charge of the battery. The lead-acid battery also shows that the battery can be recharged by reversing the direction of the current and restoring the original reactants.
Surface Chemistry
Surface chemistry is the branch of physical chemistry that studies the phenomena and processes that occur at the interface of two phases, such as solid-gas, solid-liquid, liquid-gas, etc. It also deals with the properties and behavior of surfaces and interfaces, such as surface tension, adsorption, desorption, catalysis, etc. Surface chemistry helps us to understand and manipulate the surface phenomena and processes that are important for many fields of science and technology, such as nanotechnology, materials science, environmental science, biotechnology, etc.
Barrow's Physical Chemistry 6th edition covers surface chemistry in chapters 29 to 31. It starts with an introduction to the basic concepts and principles of surface chemistry, such as surface area, surface energy, surface tension, contact angle, etc. It then explains how to apply surface chemistry to various types of surfaces and interfaces, such as solid-gas interfaces, solid-liquid interfaces, liquid-gas interfaces, colloidal systems, etc. It also discusses some advanced topics in surface chemistry, such as adsorption isotherms, adsorption kinetics, surface characterization techniques, etc.
One of the examples that Barrow uses to illustrate surface chemistry is the Langmuir adsorption isotherm. The Langmuir adsorption isotherm is a mathematical model that describes the equilibrium between adsorbed molecules and free molecules in a gas or liquid phase on a homogeneous surface. The Langmuir adsorption isotherm assumes that the adsorption sites on the surface are identical and independent, the adsorbed molecules occupy only one site each, and there is no interaction between adjacent adsorbed molecules. The Langmuir adsorption isotherm shows that the fraction of occupied sites on the surface depends on the pressure or concentration of the free molecules and a constant called the Langmuir adsorption constant. The Langmuir adsorption constant indicates the affinity and capacity of the surface for adsorption. The higher the Langmuir adsorption constant, the stronger and more favorable the adsorption is. The Langmuir adsorption isotherm can be used to determine the Langmuir adsorption constant from experimental data.
Solid State Chemistry
Solid state chemistry is the branch of physical chemistry that studies the structure, properties, and transformations of solids. It also deals with the synthesis and characterization of new solid materials, such as metals, alloys, ceramics, polymers, etc. Solid state chemistry helps us to understand and design the solid materials that have various applications in electronics, optics, magnetism, catalysis, etc.
Barrow's Physical Chemistry 6th edition covers solid state chemistry in chapters 32 to 34. It starts with an introduction to the basic concepts and principles of solid state chemistry, such as crystal structures, crystal systems, lattice parameters, unit cells, etc. It then explains how to apply solid state chemistry to various types of solids and phenomena, such as ionic solids, metallic solids, covalent solids, molecular solids, defects, diffusion, phase diagrams, etc. It also discusses some advanced topics in solid state chemistry, such as band theory, semiconductors, superconductors, nanomaterials, etc.
One of the examples that Barrow uses to illustrate solid state chemistry is the diamond structure. The diamond structure is a common type of covalent solid that consists of carbon atoms arranged in a tetrahedral network. The diamond structure has a face-centered cubic (fcc) unit cell with four atoms per cell. The
