Offering a distinct emphasis on the behavior of matter from the molecular viewpoint, this book is designed for a one-semester undergraduate course on physical chemistry for engineers and materials scientists. After a brief introductory review of the basic thermodynamic foundations, the book covers three core areas of physical chemistry - quantum chemistry, statistical mechanics, and kinetics. A final chapter provides case histories that use molecular modeling to solve engineering problems. The book includes a broad range of exercises throughout, and an Instructor's Manual is available for adopting professors. Ancillaries A detailed Instructors' Manual is available for adopting professors. Art from the book may be downloaded by adopting professors.
