Web7.18 Use the Born–Haber cycle to calculate the enthalpy of forma-tion of KBr, which crystallizes in the NaCl l attice. Use these data in the calculation: !H vap(Br2) = 29.8 kJ/mol; Br2 bond energy = 190.2 kJ/mol; and !H sub(K) = 79 kJ/mol. 7.19 Use the Born–Haber cycle to calculate the enthalpy of WebTo understand the BH cycle fully let us define the meaning of lattice energy first. It is the energy released ( exothermic, energy will have a negative value!) when a metal ion in its gaseous state combines with a nonmetal anion in its. gaseous state to form an ionic solid. The magnitude of the lattice energy relates to how stable the ionic ...
