If n = overall order of a chemical reaction. a = initial concentration of reactant. t = time required to complete a definite fraction of the reaction. Then pick out the correct relationship.

T ∝ 1/an

T ∝ 1/an - 1

T ∝ an

T ∝ 1/an + 1

T ∝ 1/an

T ∝ 1/an - 1

T ∝ an

T ∝ 1/an + 1

For a heterogeneous catalytic reaction

The catalyst does not form an intermediate complex with the reactant

The surface of the catalyst does not play an important role during reaction

Free energy of activation is lowered in the presence of catalyst, which remains unchanged at the end of 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
