About the Book

Hailed by advance reviewers as “a kinder, gentler P. Chem. text,” this book meets the needs of a full-year course in physical chemistry. It is an ideal choice for classes geared toward premedical and life sciences students. Or, as stated in a May 2001 review in Journal of Chemical Education, “this text meets these students where they are and opens the door to physical chemistry from a perspective they can appreciate.” Physical Chemistry for the Chemical and Biological Sciences offers a wealth of applications to chemical and biological problems and numerous chapter-ending exercises. Well known for his clear writing and careful pedagogical approach, Raymond Chang has developed yet another masterpiece in chemical education.
