The following energy profiles for four different reactions are shown. Which reaction is the most endothermic?

Question

Quizplus · Accepted Answer

The most endothermic reaction is the one that has the highest energy of the products compared to the energy of the reactants. In this case, reaction b has the highest energy of the products and the lowest energy of the reactants, making it the most endothermic reaction. The energy profiles for reactions a, c, and d all show a lower energy of the products compared to the energy of the reactants, indicating exothermic reactions.
