How does a catalyst increase the rate of a reaction?
A)It lowers the activation energy.
B)It is neither created nor consumed in a reaction.
C)It has nothing to do with the rate of reaction.
D)It increases the energy difference between the reactants and products.
E)It raises the activation energy of the reactants,which makes the reaction proceed faster.

Question

Quizplus · Accepted Answer

A catalyst provides an alternate reaction pathway with lower activation energy. This decreases the amount of energy needed for the reactants to reach the transition state, and therefore increases the rate of the reaction.
