Chemical Reaction Engineering
For a heterogeneous catalytic reaction

A relatively small amount of catalyst can cause the conversion of large amount of reactants which does not mean that catalyst concentration is important
Free energy of activation is lowered in the presence of catalyst, which remains unchanged at the end of reaction
The surface of the catalyst does not play an important role during reaction
The catalyst does not form an intermediate complex with the reactant
