Use the Born-Haber cycle to calculate the lattice energy of NaCl.
1st Ionization Energy for Na = 495.9 kJ/mol
2nd Ionization Energy for Na = 4,560 kJ/mol
Electron Affinity for Na = 53 kJ/mol
Electron Affinity for Cl = 349 kJ/mol
Energy to dissociate 1/2 mol of Cl2 into Cl atoms = 121.4 kJ
ΔHsublimation (Na) = 108 kJ/mol
ΔHf° (NaCl) = -411 kJ/mol
