The purpose of this module is to provide the learner with a basic understanding of the fundamentals of certain aspects of physical chemistry, in particular reaction kinetics and electrochemistry. The theoretical aspects are underpinned by suitably chosen experiments. These experiments not only amplify and reinforce the lecture content but also provide the learner with hands-on experience in a variety of experimental techniques.
Reaction Kinetics: Simple collision theory. Reaction rate. Rate laws and rate constants. Reaction order. Reaction mechanisms – elementary, consecutive (Steady State), equilibrium. Integrated rate laws. Half life. Introduction to pharmacokinetics. Arrhenius equation. Temperature dependence of reaction rates. Introduction to catalysis. Experimental methods for studying kinetics.
Electrochemistry: Application of redox reactions, Electrochemical cells. Electrode potentials and Electrochemical series. Nernst equation. Electrolytes, ionic conductivity. Ions in the body. Measurement of conductivity and applications. Debye-Huckel theory. Activity and Concentration. Kohlrausch law and Limiting Molar conductivity. Dissociation constant Ka. Voltammetric Techniques – Cyclic Voltammetry and Chronocoulometry. Randles-Sevcik and Cottrell equations.
Laboratory: Five practical classes which complement the lecture material. Details are in the School of Chemical and Biopharmaceutical Sciences Laboratory Manual.
The module will be delivered through lectures and tutorials and laboratory practicals.
