The addition of a catalyst to a chemical reaction will have what effect?

Answer 1

The catalyst will reduce the activation energy needed to convert the reactants to products.

Answer 2

The addition of a catalyst provides an alternate pathway/mechanism with a lower energy of activation, thus speeding up the reaction.

Answer 3

By definition, a catalyst speeds up a chemical reaction or, in some cases, permits one to occur where (without it) would not occur at all.
