The comprehensively updated third edition of a popular introductory statistical thermodynamics text that describes the principles and forces that drive chemical and biological processes. Now in a comprehensively updated third edition, this widely used introductory statistical thermodynamics text describes the principles and forces that drive chemical and biological processes. It demonstrates how the complex behaviors of molecules can result from a few simple physical principles, and how simple models provide surprisingly accurate insights into the workings of the molecular world. Written in an accessible, student-friendly style without compromising rigor, Molecular Driving Forces offers an excellent introduction to the subject for beginners and a valuable resource for experts. 3rd edition highlights: New chapter on the nonequilibrium dynamics of driven, adaptive and evolving systems New appendix on stochastic dynamics, including master equations and the Fokker-Planck model New vignettes on the Bayes Theorem, reverse osmosis membranes, the chemiosmotic hypothesis Comprehensively updated examples, references, and end-of-chapter questions Instructor resources available.
