Since bond energies cannot be determined directly, enthalpy cycles are used to calculate the average bond energy. …
WebBond making releases energy and is an exothermic process. The enthalpy change can be determined by using the average bond enthalpies in an energy cycle. Enthalpy required to break bonds = ∑ (bond enthalpies in reactants) Enthalpy required to make bonds = ∑ (bond enthalpies in products) Therefore: ΔH = ∑ (bond enthalpies in reactants ...
