Consider an ionic compound, MX, composed of generic metal M and generic, gaseous halogen X.The enthalpy of formation of MX is ΔHf° = –423 kJ/mol. The enthalpy of sublimation of M is ΔHsub = 119 kJ/mol. The ionization energy of M is IE = 469 kJ/mol. The electron affinity of X is ΔHEA = –301 kJ/mol. (Refer to the hint). The bond energy of X2 is BE = 161 kJ/mol. Determine the lattice energy of MX.

I tried to google it and it brought me to my own question... -_-

aaronq · Answer

$E_{Lattice~Energy} =\Delta H^o_f -(\Delta H_{sub}+IP+\dfrac{\Delta H_{BE}}{2})-\Delta H_{EA}$
