How a catalyst increases the rate of reaction
WebA catalyst increases the rate of a reaction but it is not used up in the reaction. If a catalyst is present, the reacting particles can collide more successfully with less energy … WebA catalyst increases the rate of the reaction because: They provide an alternative energy pathway that has a lower activation energy. This means that more particles have the activation energy required for the reaction to take place (compared to without the catalyst) and so the speed of the reaction increases.
