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