With what mechanism do catalysts speed up a reaction?

They lower the activation energy of the reaction.

CORRECT

They raise the activation energy of the reaction.

0

They increase the of the reaction.

0

They lower the of the reaction.

0

Explanation

Regarding chemical reactions, the activation energy is the minimum energy which must be available in a chemical system in order for reactants to participate in a chemical reaction. Catalysts speed up reactions by lowering this minimum energy. Raising it would have the opposite effect. Catalysts do not alter the of a reaction. Remember this--it is a common error to make!
