Cancelled Molecular Dynamics and Chemical Kinetics (KemiReak)
The purpose of the class is to connect the microscopic description of chemical reactions with macroscopic measurable quantities and to explore the processes responsible for chemical changes: molecular collisions, elementary reactions, surface phenomena, catalysis, absorption isotherms, theory of the activated complex and diffusion controlled reactions.The class covers elements from chemical kinetics of reaction in the gas phase, solution as well as on surfaces. The topics are statistical thermodynamics, transition state theory, reaction dynamics (elementary collision theory), unimolecular reaction, surface chemistry (adsorption, desorption, diffusion), reactions in solution, solvent effects on transition state theory, ion-reactions, electron-transfer reactions.
BSc Programme in Chemistry
After completing the course the student should be able to:
- Basic concepts of kinetics.
- Transition state theory.
- Elementary collision theory.
- Unimolecular reaction theory (RRKM theory).
- Surface reaction (adsorption/desorption, dynanics, diffusion).
- Reaction in solution (diffusion controlled reaction, solvent effects on the rate constant, electron transfer reaction).
- Use software for programming the temperature or energy dependent rate constant.
- Identify the rate laws based on detailed reaction mechanisms in homogeneous and heterogeneous reactions.
- Apply chemical kinetics to calculate the rate constant of simple and complex chemical reactions.
- Calculate rate constants for bimolecular reactions based on the transition state theory.
- Calculate the energy or temperature dependent rate constants for unimolecular reactions using RRKM theory.
- Apply the theoretical knowledge and analytical skills acquired from the course to analyze the kinetics of reactions in the gas phase, solution or on the surface.
- Analyze reaction mechanism of complex chemical reaction.
- Evaluate procedures for computing rate constants of chemical reactions.
Students are expected to take part in a whole range of classroom
activities, including lectures, presentations, discussions, and
exercises. They are also required to work on homework assignments
and reports outside regular classroom meetings.
The students need a personal pc in order to do the reports.
It is recommended that the student is familiar with the contents of the compulsory courses on the first year of the bachelor's degree program in Chemistry. In addition to qualifications within the fields of Thermodynamics.
