WebSep 12, 2024 · How does a catalyst work to make a reaction go more quickly? How does a catalyst work? A catalyst increases the rate of reaction by decreasing the activation energy. Decreased activation energy means less energy required to start the reaction. The graph below shows the energy of a reaction both with and without a catalyst present. WebThe catalyst can be either iron (II) or iron (III) ions which are added to the same solution. This is another good example of the use of transition metal compounds as catalysts because of their ability to change oxidation state. For the sake of argument, we'll take the catalyst to be iron (II) ions.
