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

Question

Quizplus · Accepted Answer

In reaction B, the energy required to break the bonds of the reactants is less than the energy released in the formation of the products. This means that the overall change in energy is negative (exothermic). Therefore, reactions A, C and D are less exothermic or endothermic in comparison to reaction B. However, without more information, we cannot determine if reactions A, C, or D are endothermic or exothermic.
