 6. Use the Born-Haber cycle to calculate the standard enthalpy of formation (∆H ) for LiCl(s) given the following data: ∆H(sublimation) Li = 155.2 kJ/mol       I₁ (Li) = 520 kJ/mol Bond energy (Cl–Cl) = 242.7 kJ/mol   EA (Cl) = 349 kJ/mol    Lattice energy (LiCl(s)) = 828 kJ/mol
(A)440 kJ/mol
(B)220 kJ/mol
(C)380 kJ/mol
(D)-380 kJ/mol
(E)-440 kJ/mol
