The topics in this course include thermodynamic models for multicomponent phase equilibrium including vapor liquid equilibrium, phase diagrams, activity models and colligative properties in both non-electrolyte and electrolyte solutions. A link between average thermodynamic properties and microstates and molecular interactions is made via a discussion of intermolecular forces and the partition function. Also covered are thermodynamic relationships to describe chemical equilibria, and basic concepts in quantum mechanics and statistical mechanics.Prerequisite(s): 540.203 Engineering Thermodynamics and either 540.202 Introduction to Chemical & Biological Process Analysis or permission of instructor. 540.xxx courses are offered through the full-time Chemical & Biomolecular Engineering Department. Course Note(s): Not for graduate credit.
