Thermodynamics II

Abstract

Introduction to the fundamentals of chemical thermodynamics and thermodynamics of mixtures.

Objective

Developing a deeper understanding of the laws of thermodynamics (introduced in Thermodynamics I). Specifically, how these laws can be extended and used to describe and analyse chemically reactive multicomponent mixtures, as well as the thermodynamics and phase equilibria of mixtures. The course covers the following topics: • Calculating mass, mole, and volume flows in reactors for mixtures, • Formulating energy balance in chemically reactive systems, • Formulating conditions for chemical equilibrium, • Deriving energy and mass balances for electrochemical energy converters (fuel cells), • Applying kinetic gas theory to heat/mass diffusion and momentum exchange, • Analysing humid air processes, • Describing ideal solution and mixture phase behavior, • Formulating thermodynamic conditions for thermal and material equilibrium.
