Thermodynamics of fluids and phase equilibrium and the fundamentals of chemical reaction engineering. Thermodynamic topics covered include: volumetric properties of fluids, thermodynamic properties of pure fluids, behaviour of solutions and phase equilibria. Chemical reaction engineering topics covered include: reaction kinetics and rate equations, reactor design, collection and analysis of kinetic data, the effect of mass transfer on chemical reaction, mixing and non-ideal flow in reactors.

This course covers core chemical engineering topics related to reaction engineering and thermodynamics. Chemical reaction engineering includes developing an understanding of chemical reaction rate, stoichiometry, reactor flow and residence time distributions as well as reactor design. The thermodynamics section covers volumetric properties of fluids, thermodynamic properties of pure fluids, solution thermodynamics, as well as phase and reaction equilibrium.
