Question

Quizplus · Accepted Answer

The gray reaction pathway represents the uncatalyzed reaction without the presence of a catalyst. The black reaction pathway in choice B shows the same reactants and products as the gray pathway, but with a lower activation energy barrier, indicating the presence of a catalyst. The other choices either do not show the effect of a catalyst or show a different reaction altogether.
