Web5 de set. de 2024 · A catalyst is a substance that decreases the activation energy needed to start a chemical reaction and as a result, also increases the rate of the chemical reaction. How do catalysts affect a chemical reaction? The rate of a reaction can be increased by adding a suitable catalyst. WebWell, first we learned that enzymes work by lowering the free energy of activation of a reaction, making it much easier for the reactants to transition and form products. And we also learned that the free energy of the reaction doesn't really change when you use an enzyme and when you don't.
