Quizplus · Accepted Answer

Arrow 1 represents the activation energy for the forward reaction, as it shows the energy required for the reactants to form the transition state. Arrow 2 represents the activation energy for the reverse reaction, as it shows the energy required for the products to form the transition state and react to form the reactants. Therefore, choice B is the best option.
