Breaking atomic bonds
WebFor example, the bond energy of the pure covalent H–H bond, D H–H, is 436 kJ per mole of H–H bonds broken: H 2 ( g) 2 H ( g) D H−H = Δ H ° = 436 kJ. Molecules with three or more atoms have two or more bonds. The sum of all bond energies in such a molecule is equal to the standard enthalpy change for the endothermic reaction that ... WebPhotodissociation, photolysis, photodecomposition, or photofragmentation is a chemical reaction in which molecules of a chemical compound are broken down by photons.It is defined as the interaction of one or more photons with one target molecule. Photodissociation is not limited to visible light.Any photon with sufficient energy can …
