WebThe average bond energy is therefore +1662/4 kJ, which is +415.5 kJ per mole of bonds. That means that many bond enthalpies are actually quoted as mean (or average) bond enthalpies, although it might not actually say so. Mean bond enthalpies are sometimes referred to as "bond enthalpy terms". WebWe 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. You can only use bond enthalpies to calculate ∆H when all substances are in the gas phase. How do I calculate enthalpy?
