The aim of this module is to introduce the students to the kinetics of complex reactions relevant to atmospheric chemistry, combustion chemistry and reactions in solution. In addition, the module is designed to extend the student’s knowledge of thermodynamics, including methods by which thermodynamic data may be derived and applied. Also there will be an introduction to dynamic electrochemistry.
Chemical kinetics:
Consecutive reactions. Steady state approximation. Classification of elementary free radical reactions. Non-chain, linear chain and branched chain reactions. Introduction to photochemical kinetics. Reversible reactions experimental techniques, theories of reaction rates. Reactions in solution
Thermodynamics:
Review of second law. Gibbs and Helmholtz free energies. Gibbs Helmholtz. Van’t Hoff isochore. Third law of thermodynamics. Determination and uses of thermodynamic data in applied situations.
Dynamic electrochemistry
Mass transport modes. Potential step experiment. Introduction to electrode kinetics, the Butler-Volmer equation. Voltammetry: Peak potential and peak current, diffusion and adsorption control, reversible systems.
A selection of relevant practical’s pertaining to the theory will be run by the students.
The module is delivered through lectures (20 hrs), tutorials (4 hrs) and laboratory practical sessions (15 hrs).
