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

Question

Quizplus · Accepted Answer

In pathway B, the addition of the black catalyst lowers the activation energy required for the reaction to occur, leading to a faster rate and a higher yield of product compared to the uncatalyzed reaction shown in gray. This is evident by the lower energy barrier in the presence of the catalyst. The other pathways either do not show the effect of a catalyst or show incorrect representations of catalysts.
