12.2 Exothermic and endothermic reactions - Siyavula In an endothermic reaction, 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) + H 2 O (ℓ) → CO (g) + H 2 (g) Δ H > 0. Some of the information relating to exothermic and endothermic reactions is summarised in Table 12.1.
