Physical Chemistry offers a comprehensive collection of physical principles and mathematical techniques for majors, non-majors, and chemical engineers. Lucidly written, logically organized, and widely used, it offers thorough, balanced coverage of thermodynamics, kinetics, quantum mechanics, and statistical mechanics. Recognizing the benefits of computer algebra software programs, the author has shifted his emphasis from formula derivation to numerical examples. Five appendices review the mathematics used in problem solving. Throughout the text students will find a greater number of real-world examples and problems than ever before.
