This book provides a sound foundation for understanding abstract concepts of phase and reaction equilibria (e.g. partial molar Gibbs energy, fugacity, and activity), and shows how to apply these concepts to solve practical problems using numerous clear examples. It also presents numerical methods necessary for solving real-world problems as well the basic mathematics needed, facilitating its use as a self-study reference work. In the example problems requiring MATHCAD® for the solution, the results of the intermediate steps are given, enabling the reader to easily track mistakes and understand the order of magnitude of the various quantities involved.

Key Features

  • Clear layout, coherent and logical organization of the content, and presentation suitable for self-study
  • Provides analytical equations in dimensionless form for the calculation of changes in internal energy, enthalpy, and entropy as well as departure functions and fugacity coefficients
  • Includes up-to-date information, comprehensive in-depth content and current examples in each chapter
  • Includes many well organized problems (with answers), which are extensions of the examples enabling conceptual understanding for quantitative/real problem solving
  • Includes the mathematical background required for solving problems encountered in phase and reaction equilibria


Graduate and undergraduate students in chemical, environmental, petroleum, and metallurgical engineering departments; graduate and undergraduate students in the departments of chemistry, biotechnology, food science and technology, and materials science as well as professional engineers in the above areas
