Answer:
Catalyst can decrease the activation energy of an reaction.
Explanation:
Catalyst are the substances that can increase the speed of a chemical reaction without itself undergoing any change during the reaction. Activation energy is the minimum amount of energy required to start a chemical reaction.
Catalyst decreases the activation energy of the reactions so that reactants can be converted into products in less time. Catalyst forms intermediates during the reaction that requires less activation energy to convet into the product.
Thus, catalyst increases the rate of a reaction by decreasing the activation energy.
