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. the bond energy of x2 is be = 161 kj/mol. determine the lattice energy of mx.
