WebEnergy diagrams for endothermic and exothermic reactions In the case of an endothermic reaction, the reactants are at a lower energy level compared to the products—as shown in the energy diagram below. In other words, the products are less stable than the reactants. WebJustification: Both of the graphs show an endothermic reaction, except reaction 2 has a much larger change in enthalpy, thus more energy is needed for the reaction to occur and it is considered to be more endothermic. The graphs do show that H 2 S has a higher potential energy than CO 2. Having a higher potential energy (H) does not mean than
