The reaction profiles for four reactions are shown below. Which one has the largest activation energy?

Question

Quizplus · Accepted Answer

The activation energy is the energy required to reach the transition state. In the given reaction profiles, we can see that the profile with the steepest slope indicates a higher activation energy. In this case, profile II has the steepest slope, indicating that it has the largest activation energy.
