A catalyst is a surface that increases the rate of a chemical reaction without itself being used up. It remains unchanged chemically providing an alternate path for the reaction at an accelerated rate by lowering the activation energy. 

The catalyst forms an activated complex of lower potential energy, with the reactants by which more molecules are able to cross the barrier per unit time.

So, Statement-1 is true, statement-2 is true and statement-2 is  correct explanation for statement-1.

Option 2 is correct.
