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". WebAug 21, 2024 · The bond enthalpy of the H-F bond. Because the fluorine atom is so small, the bond enthalpy (bond energy) of the hydrogen-fluorine bond is very high.
