WebJul 14, 2024 · Assume bond dissociation energy is 423 kJ/mol Δ H r = 946 k J / m o l + 3 ⋅ 423 k J / m o l − 6 ⋅ 272 k J / m o l = positive value So it can't be 423 kJ/mol because the reaction is exothermic. If you complete the math for a bond energy of 141 kJ/mol, the numerical answer is -263 kJ/mol for the reaction enthalpy. WebEnthalpy values use the mean bond energy which is an average over different molecules. We can use the mean bond energy to calculate the ΔH of a reaction by using the formula: ΔH = Σ bond energies broken - Σ bond energies made.
