Average bond energy summation

Method of Craven [50] This average bond energy summation method (ABES) is a simplification of the method described by Sanderson [55]. The reaction enthalpy is calculated by subtracting the total bond energies present before the reaction from the total bond energies of the products.

The approximate exothermicity of a chemical reaction or decomposition can be predicted firrm the atomization energies of the reactants and the assumed products. The atomization energies of many compounds can be determined by average bond energy summation using published data -. ...

Representative single bond values were given in Table 10. Summation of such energies to obtain average values for molecules applies only when the constituent atoms exhibit their normal covalences and is subject to Ihe exceptions already slated.
