Energy and Entropy

This book is an overview of classical thermodynamics, statistical thermodynamics, non-equilibrium and stationary state thermodynamics. This comprehensive work is the first book outside of specialized monographs to approach flow systems and irreversible thermodynamics for advanced undergraduate or introductory graduate courses in thermodynamics in chemistry, physics, biophysics, and engineering programs. Instructors for those courses will find in this book transparent models that clarify a broad range of difficult physical and mathematical concepts, including:

• Cooligative properties and solution thermodynamics
• Chemical potential for equilibrium systems
• Continuous energy systems
• Transition to non-equilibrium systems through statistical chemical kinetics
• Bose-Einstein statistics in conjunction with unimolecular reaction rate theory
• Irreversible thermodynamics with both time and spatial dependence
• Basic stationary state processes.

The study of thermodynamics is often limited to classical thermodynamics where minimal laws and concepts lead to a wealth of equations and applications. The resultant equations best describe systems at equilibrium with no temporal or s- tial parameters. The equations do, however, often provide accurate descriptions for systems close to equilibrium. . Statistical thermodynamics produces the same equilibrium information starting with the microscopic properties of the atoms or molecules in the system that correlates with the results from macroscopic classical thermodynamics. Because both these disciplines develop a wealth of information from a few starting postulates, e. g. , the laws of thermodyamics, they are often introduced as independent disciplines. However, the concepts and techniques dev- oped for these disciplines are extremely useful in many other disciplines. This book is intended to provide an introduction to these disciplines while revealing the connections between them. Chemical kinetics uses the statistics and probabilities developed for statistical thermodynamics to explain the evolution of a system to equilibrium. Irreversible thermodynamics, which is developed from the equations of classical thermodyn- ics, centers on distance-dependent forces, and time-dependent ?uxes. The force ?ux equations of irreversible thermodynamics lead are generated from the intensive and extensive variables of classical thermodynamics. These force ?ux equations lead, in turn, to transport equations such as Fick's ?rst law of diffusion and the Nernst Planck equation for electrochemical transport. The book illustrates the concepts using some simple examples.
