Understand the concept of activation energy: Activation energy is the minimum energy required for a chemical reaction to occur.
Identify the role of each option: Reactants are the starting substances, products are the substances formed, inhibitors slow down reactions, and catalysts speed up reactions.
Recall that a catalyst is a substance that increases the rate of a chemical reaction by lowering the activation energy without being consumed in the process.
Recognize that lowering activation energy means the reaction can proceed faster or at a lower temperature.
Conclude that among the given options, the catalyst is the substance that lowers the activation energy of a chemical reaction.
