WebNov 4, 2024 · Bond energy is defined by the sum of all of the bonds broken minus the sum of all of the bonds formed: ΔH = ∑H (bonds broken) - ∑H (bonds formed). ΔH is the change in bond energy, also referred to as the bond enthalpy and ∑H is the sum of the bond energies for each side of the equation. [2] This equation is a form of Hess’s Law.
