What is the relation between the enthalpy of reaction and bond enthalp

1.	What is the relation between the enthalpy of reaction and bond enthalpy?
Answer» A chemical reaction involves the breaking of bonds in reactants and formation of new bonds in products. The heat of reaction (enthalpy change) depends on the values of the heat needed to break the bond formation .Thus (Heat of reaction = (Heat needed to break the bonds in reactants – Heat liberated to from bonds in products). ΔH^O = Bond energy in (to break the bonds) X Bond energy out (to form the bonds) = Bond energy of reactants – Bond energy of products.
