The following figure shows an uncatalyzed reaction path (dashed line).Which of the other reaction paths shows the effect of a catalyst?

Question

Quizplus · Accepted Answer

The reaction path in figure B is lower than the uncatalyzed reaction (dashed line) which indicates that the activation energy required for the reaction has been lowered. This is the effect of a catalyst. The other reaction paths (A, C, and D) are all higher than the uncatalyzed reaction path, which means they require more energy to occur and are therefore not the effect of a catalyst.
