Bond Dissociation Enthalpy: Introduction and its Effects

The bond-dissociation energy (BDE, D0, or DH°) is one measure of the strength of a chemical bond A−B. It can be defined as the standard enthalpy change when A−B is cleaved by homolysis to give fragments A and B, which are usually radical species. The enthalpy change is temperature-dependent, and the bond-dissociation energy is often defined to be the enthalpy change of the homolysis at 0 K (absolute zero), although the enthalpy change at 298 K (standard conditions) i… strike estate agents sutton in ashfieldWebJan 14, 2024 · Calculation of the BDE. The BDE for a molecule A-B is calculated as the difference in the enthalpies of formation of the products and reactants for homolysis.
