เนื้อหาย่อ : The objective of this book is to make the concepts and methods of physical chem- istry clear and interesting to students who have had a year of calculus and a year of physics. The underlying theory of chemical phenomena is complicated, and so it is a challenge to make the most important concepts and methods understandable to undergraduate students. However, these basic ideas are accessible to students, and they will find them useful whether they are chemistry majors, biologists, engi- neers, or earth scientists. The basic theory of chemistry is presented from the view- point of academic physical chemists, but many applications of physical chemistry to practical problems are described. One of the important objectives of a course in physical chemistry is to learn how to solve numerical problems. The problems in physical chemistry help em- phasize features in the underlying theory, and they illustrate practical applica- tions. FEATURES NEW TO THIS EDITION In this edition there are two types of problems: problems that can be solved with a hand-held calculator and a new set of COMPUTER PROBLEMS that require a personal computer with a mathematical application installed. There are two sets of problems of the first type. The answers to problems in the first set are given in the back of the textbook, and worked-out solutions to these problems are given in the Solutions Manual for Physical Chemistry. The answers for the second set of problems are given in the Solutions Manual. In the two sets of problems that can be solved using hand-held calculators, some problems are marked with an icon to indicate that they may be more conveniently solved on a personal computer with a mathematical program. But the 136 new COM- PUTER PROBLEMS are problems that require a personal computer with a mathematical application such as MathematicaTM, MathCadTM, MATLABTM, or MAPLETM installed. The recent development of these mathematical ap- plications makes it possible to undertake problems that were previously too difficult or too time consuming. This is particularly true for two- and three- dimensional plots, integration and differentiation of complicated functions, and
