Module summaryThis course will cover two fundamental parts of physical chemistry, namely chemical kinetics and thermodynamics. It builds on the concepts of energy storage, states of matter and chemical change introduced at level 1. The module is concerned with the measurement and understanding of the rates and energetics of chemical reactions, and illustrated using the context of societally important applications of chemical kinetics and thermodynamics, for example atmospheric chemistry and combustion.
ObjectivesTo provide students with an underpinning understanding of the foundations of physical chemistry through a study of chemical kinetics and thermodynamics.
After completing the module, students should demonstrate:
1) 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;
2) an understanding of and ability to solve problems involving theories describing pressure and temperature dependence of reaction kinetics, including collision theory and a basic understanding of transition state theory;
3) an understanding of and ability to solve problems involving the mechanism of reactions occurring in solution, including diffusion and activation-controlled reactions, and the role of the solvent cage in facilitating reaction;
4) an understanding of and ability to solve problems involving the kinetics of complex processes, including parallel reactions, chain reactions, free-radical polymerisation, explosions, enzyme reactions;
5) an awareness of experimental techniques used to study fast reactions, including an introduction to laser-based techniques;
6) an understanding of and ability to solve problems involving chemical potential, ideal and non-ideal behaviour and the use of activity and activity coefficients, including thermodynamics of ideal/non-ideal liquid mixtures and solutions;
7) an understanding of and ability to solve problems involving relationships between p,V,T and different thermodynamic measures of energy/chemical potential;
8) an understanding of and ability to solve problems involving the extent of reaction chi, and its relation to the chemical potential, change in Gibbs free energy and position of equilibrium;
9) an understanding of and ability to solve problems involving the temperature dependence of the equilibrium constant using reaction isotherms, including application and understanding of the van't Hoff equation;
10) an understanding of and ability to solve problems involving solution equilibria including acid/base, precipitation and complexation equilibria.
