A catalyst can speed up the rate of a given chemical reaction by lowering the activation energy required for the
reaction to occur.
A catalyst is a substance that regulates the rate at which a chemical reaction occurs. A catalyst can either inhibit or promote a chemical reaction.
A catalyst is characterized by being involved in a chemical reaction but not being used up. A catalyst increases the rate of a chemical reaction by lowering the activation energy, which is the energy required for the reaction to start.
