Bond Enthalpy and Heat of reactions

First law of Thermodynamics | Enthalpy | Heat capacity | Standard enthalpy change of a reaction

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

Enthalpy change of the reaction 2H(g) to H_(2)(g) is -104 kcal The H-H bond dissociation energy is

Enthalpy chane of a reaction with be equal to

The terms bond enthalpy and bond dissociation enthalpy stand for one and the same thing.
