Question

Quizplus · Accepted Answer

A catalyst provides a new pathway (mechanism) for the reaction to occur through. This new pathway typically has a lower activation energy, which allows for the reaction to occur more easily and quickly. A catalyst does not increase the rate of collisions between reactant molecules nor does it provide reactant molecules with more energy. Additionally, a catalyst does not slow down the rate of the back reaction.
