WebA catalyst is a substance that speeds up a chemical reaction without being used up or chemically changed. Catalysts are usually specific to a particular reaction. WebA catalyst does this by lowering the activation energy, which we explain in the next section. Catalysts work by providing an alternative pathway for the reaction to follow that has that lower activation energy, which makes it easier for the reactants to form the products. This allows the reaction to occur more quickly and efficiently. highstone homes limited
