WebbIn an endothermic reaction, ΔH Δ H is greater than zero because the energy of the reactants is less than the energy of the products. Energy is absorbed in the reaction. For example: C (s) + H2O (l) → CO (g) + H2(g) ΔH > 0 C (s) + H 2 O (l) → CO (g) + H 2 (g) Δ H > 0. Some of the information relating to exothermic and endothermic ... WebbFor exothermic reactions, the reactants are drawn above the products because their energy is greater. However, for endothermic reactions, the reactants are drawn below the products.
