Description:
| Aims: To introduce and develop key concepts in physical chemistry, in particular those of importance in chemical engineering processes.
Learning Outcomes: After successfully completing this unit students should be able to:
* Understand energy conservation in closed, open and reacting systems.
* Understand the phase behaviour of substances and how to use the phase rule.
* Understand the concepts of chemical potential, ideal and non-ideal conditions, and activity coefficients.
* Calculate changes in enthalpy, entropy, Gibbs' free energy, and equilibrium constants of chemical reactions.
* Understand the basic principles of electrochemistry.
* Understand the basic principles of the physical chemistry of interfaces
Skills: Analysis and problem solving (taught/facilitated and assessed).
Content:
* Gases; liquids and solutions; solids; polymers; bio-molecules.
