Chemistry

Consider an ionic compound, MX2 , composed of generic metal Mand generic, gaseous halogen X . The enthalpy of formation of MX2is Δ?∘f=−677 kJ/mol. The enthalpy of sublimation of M is Δ?sub=161kJ/mol. The first and second ionization energies of M are IE1=647kJ/mol and IE2=1377 kJ/mol. The electron affinity of X is Δ?EA=−339kJ/mol. (Refer to the hint). The bond energy of X2 is BE=221kJ/mol. Determine the lattice energy of MX2 . Δ?lattice= kJ/mol
