Description

This unit will investigate the impact of the fundamental laws of thermodynamics on steady and unsteady state processes. Phase and chemical equilibrium will also be investigated in the context of the Gibbs free energy of a system. Methods to critically analyse data and/or equations related to particular processes will be explored. Students will be equipped with the tools and knowledge to tackle unfamiliar problems using these principles.

Prerequisite Rule

Students must pass 1 units from ENS2160

Learning Outcomes

On completion of this unit students should be able to:

1. Apply the first and second law of thermodynamics to steady/unsteady state systems and reacting/non-reacting systems.
2. Calculate the extent of reaction or reaction potential for a given reaction and set of conditions.
3. Choose a suitable equation of state for a given situation and apply equations of state in process calculations.
4. Explain the basis for all chemical and phase equilibrium and explain what partial molar properties are and why they are important for equilibrium calculations.
5. Explain what excess properties are and the origins of excess properties.
6. Explain what ideal and non-ideal solutions are, their causes, and the effects of non-ideality on phase and chemical equilibrium.
7. Use activity models in phase equilibrium and reaction equilibrium calculations and be able to choose an appropriate model for a given situation.
8. Use commercial software to calculate the equilibria, phase and reaction of multi-component systems, and analyse the impact of process conditions on the equilibria.
9. Use phase equilibrium charts and pre-dominance diagrams to perform equilibrium process calculations.

Unit Content

1. 1st and 2nd laws of thermodynamics with applications.
2. Chemical equilibrium in gas phase, liquids and gas-liquid mixtures.
3. Criteria for equilibrium.
