Which of the following determines the rate of a reaction?

Question

Quizplus · Accepted Answer

The rate of a reaction is determined by the activation energy, which is the energy barrier that must be overcome for the reaction to occur. A higher activation energy impedes the reaction, while a lower activation energy facilitates it. The other choices represent chemical reactions but do not provide information about the rate of the reaction. The overall change in free energy (E) can provide information about the spontaneity and directionality of a reaction, but not its rate.
