Explanation:
Bond breaking, whether homolytic or heterolytic, requires energy to be provided. The energy bend energy of a Cl-Cl bond is about +243kJ/mol, so this is the amount of energy that has to be supplied to break a mole of Cl-Cl bonds.
If we divide this amount by Avogadro's number we get the energy required to break one Cl-Cl bond, and using E=h
