| Description: | Aims: Second half of year long unit: To introduce and expand on advanced physical chemistry methods in kinetics, spectroscopy, surfaces and quantum mechanics. Learning Outcomes: After studying this Unit, students should be able to: * Account in kinetic terms for the mechanism of reactions in liquids; * Describe the effect of light on some chemical reactions and account for the rates of photochemical processes; * Describe and define the types of adsorption at solid surfaces; * Explain the qualitative and quantitative basis of catalysis and physical adsorption; * Define surface tension and solve simple problems involving its application; * Define and interpret the forces between two colloids. Skills: Numeracy (F, A), Problem solving (T, F, A), Independent working (F). Content: Theoretical treatments of reaction kinetics and examples of their application e.g. Reactions in solution. Diffusion and activation control, the "cage" effect. Experimental methods for studying reactions: Basic photochemical methods and processes. Applications of photochemistry. Kinetics of photochemical reactions. Introduction to surfaces. chemisorption versus physisorption. adsorbed amounts. Types of isotherms: Langmuir Isotherm. determination of heat of adsorption,BET isotherm: Introduction to heterogeneous catalysis. Kinetics of catalysis. Langmuir Hinshelwood mechanism. Eley Rideal mechanism. Catalysis examples Molecular basis and consequences of surface tension. Colloid stability. Micellisation. Gibbs equation. |
