Which of the following reaction pathways shows the effect of a catalyst (black) on an uncatalyzed reaction (gray)?

Question

Quizplus · Accepted Answer

The gray line represents the uncatalyzed reaction and the black line represents the catalyzed reaction. Pathway B shows a lower activation energy with the catalyst present, indicating that the catalyst has lowered the energy required to initiate the reaction. The other pathways do not show a noticeable difference in activation energy between the catalyzed and uncatalyzed reactions.
