Topics 6
- Scope of chemical kinetics; slow and fast reactions explained by bonds; average and instantaneous rate (graphical)
- Factors affecting rate: nature of reactants, surface area, concentration, temperature, catalyst and radiation; law of mass action and active mass
- Rate law and rate constant; order of reaction as an experimental quantity; units of k
- Zero order reactions: rate equation and units
- First order reactions: derivation of the integrated rate equation; half-life; independence of k from initial concentration
- Molecularity; elementary and complex reactions; mechanism and rate-determining step; order versus molecularity
