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.
They increase the 
They lower the 
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
