Question

Use the Born Haber cycle to calculate the lattice energy of CaCl2(s). Given the following data: Heat of sublimation of Ca = 179 kJ/mol Bond dissociation energy of Cl2 = 243 kJ/mol EA of Cl = -349 kJ/mol First Ionization Energy, IE1 of Ca = 590 kJ/mol Second Ionization Energy, IE2 of Ca = 1145 kJ/mol Net energy change for the formation of CaCl2 from its elements in their standard states (Hf) = -796 kJ/mol
