Molecular Thermodynamics [PDF ebook] 

Evolved from Mc Quarrie and Simon’s best-selling textbook, Physical Chemistry: A Molecular Approach, this text focuses in on the thermodynamics portion of the course. Although many of the chapters in Molecular Thermodynamics are similar to chapters in the larger physical chemistry text, new material has been added throughout along with three entirely new chapters on "The Energy Levels of Atoms and Molecules, " "Thermodynamics of Electrochemical Cells, " and "Nonequilibrium Thermodynamics." The text also includes five short "Math Chapters, " each with a special set of problems that will help students review and summarize the mathematical tools required to master the material. Worked examples and chapter-ending problems with solutions are also included throughout the book.
