The average value of the gas-phase
bond dissociation energies (usually at a temperature of
)
for all
bonds of the same type within the same
chemical species. The mean bond energy for methane, for example, is one-fourth the
enthalpy of reaction for:
Tabulated bond energies are generally values of bond energies averaged over a number
of selected typical chemical species containing that type of bond.
