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. 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. WebAug 15, 2024 · A catalyst is a substance which speeds up a reaction, but is chemically unchanged at its end.
