This is a unique book with a different aim from other books on the subject. The idea is to provide readers with the “big picture” first, yet at a level that helps further the study of physical chemistry. The text covers all the important topics in physical chemistry — thermodynamics, statistical thermodynamics, quantum chemistry, and chemical kinetics — staying rigorously close to the basic theory, using appropriate mathematics but avoiding long derivations. Moreover, the book is supplemented by a CD-ROM to make it more comprehensive, interactive and useful for a wider audience. The CD-ROM contains examples, extended discussion, exercises and details of important derivations to reinforce understanding of physical chemistry.
