Pre-requisite qualifications
Level 2 in a Chemistry programme or equivalentThis module is not approved as a discovery module
Objectives
On completion of this module, students should be able to:(i) Describe the energy level structure within molecules for rotational and vibrational motion, and how molecular parameters (bond lengths, force constants) can be obtained from analysis of spectroscopic experiments.
(ii) Describe the distribution of population amongst energy levels and calculate partition functions for translational, rotational and vibrational motion
(iii) Apply statistical mechanics to the calculation of thermodynamic properties of gases, liquids and solids (heat capacitites, equilibrium constants)
(iv) Describe theoretical approaches to reaction kinetics, understand the links between thermodynamics and kinetics, and calculate rate coefficients using transition state theory (TST) and describe other applications of TST
(v) Describe the link between thermal and microscopic rate coefficients, the partitioning of reaction enthalpy into the products of exothermic reactions (and how this is measured), and features of the potential energy surface that control energy disposal (reaction dynamics)
(vi) Describe the kinetics of surface reactions and the applications of heterogeneous catalysis in the chemical industry
(vii) Describe other applications of kinetics
