Question: Consider an ionic compound, M * X _ { 2 } composed of generic metal M and genericgaseous halogen X . The enthalpy of formation

Consider an ionic compound, M*X_{2} composed of generic metal M and genericgaseous halogen X. The enthalpy of formation of M*X_{2} is Delta H f ^*=-987 kJ/mol. The enthalpy of sublimation of M is Delta H cub =125 kJ/mol. The first and second ionization energies of M are I*E_{1}=677kJ / m * ol and I*E_{2}=1.39*10^3* kJ / m * ol The electron affinity of X is Delta H E Lambda =-351 kJ/mol.( Refer to the hint.) The bond energy of X_{2} is BE =201kJ / m * ol Determine the lattice energy of M*X_{2}
