Endothermic Reaction Energy Level Diagram: Endothermic reactions are depicted in a basic energy level diagram below. The activation energy is the amount of energy that must be delivered to the reactants for them to break through the energy barrier and react. In an endothermic reaction, the result has higher potential energy than the reactants. An endothermic reaction must have a positive change in enthalpy. That is, Delta"H">0. This means that the system absorbs heat. To represent the positive change in enthalpy, the potential energy of the reactants must be LOWER than that of the products. Notice how the end of the "hump" is higher than the beginning, showing how the system gained energy during the course of the reaction. Since the potential energy of the products is higher than the potential energy of the reactants, the reaction is endothermic and the enthalpy (E(C)-E(A)) has a positive sign.The activation energy (E(B)-E(A)) is positive as well.. We have a diagram showing the potential energy changes for a reaction pathway.. Point A represents the potential energy of the reactants.
