Cross-listing Dept.
Chemical kinetics and dynamics remains one of the most exciting areas in modern chemistry. A student that successfully
completes this course will develop skills in methods that allow the quantitative description of chemical change. While
many portions of the undergraduate chemistry curriculum emphasize descriptive and qualitative treatments, the present
course develops a much more mathematical and computational formulation. Students will learn to construct predictive
models that describe the time evolutions of chemical concentrations and other attributes of kinetic systems including ab
initio theories of rate coefficients.
A student completing this course will learn to (1) compute the rates of chemical reactions using ab initio data using
statistical theories of reaction, transition state theory and RRKM theory, (2) analyse the behaviour of complex reaction
networks using methods such as sensitivity analysis, and (3) construct kinetic models to represent problems of interest in
physical chemistry and catalysis

this is a team teaching or module course.)
1. Mass action kinetics. The construction of rate laws for elementary reactions in gas phase systems is discussed.
The structure of kinetic equations for multi-step chemical mechanisms is presented including the role of conservation
laws and micro-reversibility. Approximate solutions of the kinetic equations using the quasi-steady state approximation is
presented. Network analysis and sensitivity analysis is discussed for complex mechanisms. Models for chain branching
chemical reactions are presented. (4 hrs)
2. Evaluation of rate coefficients. Transition State Theory is derived for bimolecular chemical reactions. A brief
review of statistical thermodynamics, kinetic theory of gases, and potential energy surfaces is presented as a necessary
introduction to the formalism. Additional topics of discussion include the theory of quantum tunnelling, isotope effects,
and thermodynamics formulation. (4 hrs)
3. Unimolecular reactions and energy transfer. The RRKM theory of unimolecular reaction rates is derived. The
role of intramolecular and intermolecular energy transfer is discussed. State counting algorithms are introduced. (4 hrs)
4. Reactions in condensed phase environments. The theory of diffusion controlled reactions is presented for
chemical reactions occurring in solution phase. Chemical reactions on catalytic surfaces is analysed. The rates of
electron transfer reactions in condensed phase is modelled using the Marcus theory of electron transfer. (4 hrs)
