This course covers the application of laws of thermodynamics to engineering problems related to chemical equilibrium and solutions. Topics include changes in thermodynamic properties of pure substances and their inter-relationships, fugacity and fugacity coefficient, partial molal properties of mixtures, mathematical models for the chemical potential, ideal and non-ideal solutions, activity and activity coefficient, Gibbs-Duhem equation, excess properties of mixtures, criteria for phase equilibria in multicomponent non-reacting systems, vapour-liquid equilibria and solubility, and chemical reaction equilibria. The equilibrium constant and its variation with pressure, temperature, and composition is examined. PREREQ: ENGR 2036. (lec 3, tut 1) cr 3.
