1. For a heterogeneous catalytic reaction
(A): a relatively small amount of catalyst can cause the conversion of large amount of reactants which does not mean that catalyst concentration is important.
(B): free energy of activation is lowered in the presence of catalyst, which remains unchanged at the end of reaction.
(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.

MCQ->Rate constant for a first order reaction does not depend upon reaction time, extent of reaction and the initial concentration of reactants ; but it is a function of reaction temperature. In a chemical reaction, the time required to reduce the concentration of reactant from 100 gm moles/litre to 50 gm moles/litre is same as that required to reduce it from 2 gm moles/litre to 1 gm mole/litre in the same volume. Then the order of this reaction is....
