Objectives

To provide students with an underpinning understanding of the foundations of physical chemistry through a study of chemical kinetics and thermodynamics

Learning outcomes
- Demonstrate an understanding of both the possibilities for and the rates of chemical and physical change, and of the thermodynamic and kinetic concepts that are most relevant for chemists;
- Understand how energy is stored and distributed in atoms and molecules;
- Understand the relationship between kinetics and thermodynamics;
- Analyse the kinetics of elementary and complex reactions and use kinetic information to understand the mechanisms of chemical reactions;
- Understand the use of chemical potential as a general criterion for phase and chemical equilibrium and be able to calculate the composition of equilibrium mixtures under ideal and non-ideal thermodynamic conditions.


Syllabus

The links between kinetics and equilibria. Experimental methods to study kinetics, in particular for fast reactions. Theories of bimolecular reactions: collision theory and transition state theory. Pressure dependence of unimolecular and recombination reactions. Kinetics of reactions in solution. Kinetics of complex reactions: Chain reactions, polymerisation, explosions and enzyme reactions.

The chemical potential and the criteria for chemical and phase equilibria. Molecular partition functions, Maxwell relations, Ideal and non-ideal systems, activity coefficients, solutes and solvent conventions. Chemical equilibrium, calculation of yields. Phase equilibrium, Clausius-Clapeyron. Colligative properties, osmotic pressure.
