a) Draw the Born Haber cycle
b) Calculate the crystal lattice energy
For MgF2
ΔH sublimation Mg = +148 kJ/mol ΔH°f
MgF2 = -1.123 kJ/mol
ΔH dissociation F2 = +159 kJ/mol
ΔH first ionization Mg = +738 kJ/mol
ΔH second ionization Mg = +1,450 kJ/mol
ΔH electron affinity F = -328 kJ/mol
ΔH lattice energy MgF2 = ???
