What is the effect of a catalyst on the rate of a reaction?

WebFeb 18, 2024 · A catalyst is simply a chemical that makes a chemical reaction go faster without itself changing in the process. It's a bit like an athletics coach who stands by the side of the track and shouts at the runners to go faster. The coach doesn't run anywhere; he just stands there, waves his arms about, and makes the runners speed up. WebA catalyst speeds up both the forward and back reactions by exactly the same amount. Dynamic equilibrium is established when the rates of the forward and back reactions become equal. If a catalyst speeds up both … WebA catalyst provides an alternative pathway for the reaction, that has a lower activation energy. This means there are now more particles with the activation energy and so the rate will increase. Increasing the temperature has no effect on the activation energy. The temperature changes the amount of energy the particles have. chilling hot plate process station
