Consider an ionic compound, MX,, composed of generic metal M and generic, gaseous halogen X. The enthalpy of formation of MX, is AH; = -693 kJ/mol. The enthalpy of sublimation of M is AHsut = 121 kJ/mol. The first and second ionization energies of M are IE, = 797 kJ/mol and IEs = 1435 kJ/mol. The electron affinity of X is AHEA = -315 kJ/mol. (Refer to the hint.) The bond energy of X, is BE = 191 kJ/mol.Determine the lattice energy of MX,
