Problem

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
