Question

Draw the Born-Haber cycle for the formation of solid sodium chloride and use the following data to calculate the lattice energy.

Na(s) → Na(g)                                 ΔH° = 109 kJ/mol

Cl2(g) → 2Cl(g)                                ΔH° = 243 kJ/mol

Na(g) → Na+(g) + e-                                ΔH° = 496 kJ/mol

Cl(g) + e- →  Cl-(g)                           ΔH° = -349 kJ/mol

Na(s) + 1/2Cl2(g) → NaCl(s)           ΔH° = -411 kJ/mol
