"WebIn an exothermic reaction, by definition, the enthalpy change has a negative value: ΔH = H products - H reactants < 0. where a larger value (the higher energy of the reactants) is subtracted from a smaller value (the lower energy of the products). For example, when hydrogen burns: 2H 2 (g) + O 2 (g) → 2H 2 O (g) ΔH⚬ = −483.6 kJ/mol See also " - Exothermic change science definition
