This lecture covers the mechanism and kinetics of chain polymerisation, including initiation, propagation, and termination steps. It also discusses the rate law for the formation of polymer chains, considering the presence of inhibitors and competitive inhibition. The instructor explains the concepts using the hydrolysis of benzoylglycylglycyl-L-phenylalanine as an example, highlighting the effects of inhibitors on enzyme reactions. Various kinetic parameters are computed to analyze the reaction dynamics.
