Which of the following statements is true?

Question

Quizplus · Accepted Answer

The size of the activation energy tells us about the reaction rate. Activation energy is the minimum energy required for a reaction to occur. The higher the activation energy, the slower the reaction rate, whereas the lower the activation energy, the faster the reaction rate. Therefore, option B is the correct statement as compared to the other given options. Option A is wrong because activation energy only tells us about the minimum energy required to start a reaction and not about the mechanism. Option C is incorrect because a slow reaction may have high activation energy. Option D is incorrect because a fast reaction may have low activation energy.
