Factors Affecting Reaction Rates

How 5 major factors influence rate of reaction; Temperature, Concentration, Surface Area, Catalyst and the nature of the Reactants. This lesson also looks at how Temperature and Catalysts effect the kinetics of a reaction, using Boltzmann diagrams of the molecular Kinetic Energy.
