The collision theory shows that the rate of a chemical reaction depends on the frequency of the effective collisions between reactant particles. So any factor that can influence one or all following · The energy content of the particles · The frequency of the collision of the particles · The activation energy of the chemical reaction Can also affect the rate of chemical rate and such factors are · Nature of reactants · Concentration / pressure(for gas) of the reactants · Surface area of reactants · Temperature of reaction mixture · Presence of light · ...
