What is meant by bond dissociation enthalpy?

Bond dissociation enthalpy and bond enthalpy are not the same for

When is bond dissociation enthalpy equal to bond enthalpy?

Enthalpy change of Atomisation | Bond enthalpy and Bond Dissociation Enthalpy | Standard Enthalpy change of Phase Transformation | Standard Enthalpy change of lattice and Ionisation | Standard Electron Gain Enthalpy | Standard Enthalpy Change of Solution

The bond dissociation energy of a diatomic molecule is also called bond energy. However, the bond dissociation energy depends upon the nature of bond and also the molecule in which the bond is present. The bond energy N-H bind in NH_(3) is equal to one-third of the energy of dissociation of NH_(3) because there are three N-H bonds and those of C-H bond in CH_(4) is equal to one-fourth of the energy of dissociation of CH_(4) Heat of a reaction = Bond energy of reactants - Bond energy of products In which of the following, the bond enthalpy and bond dissociation enthalpy are identical ?
