Calculate the lattice energy for NaCl(s) using a Born-Haber cycle and the following information:

   NaCl(s) → Na+(g) + Cl-(g)   ?
   Na(s) + 1/2 Cl2(g) → NaCl(s)   -411.0 kJ/mol
   Na(s) → Na(g)   +107.3 kJ/mol
   Na(g) → Na+(g) + e-   +495.8 kJ/mol
   1/2 Cl2(g) → Cl(g)   +121.7 kJ/mol
   Cl(g) + e- → Cl-(g)   -348.6 kJ/mol

A) +34.8 kJ/mol
B) +690.3 kJ/mol
C) +787.2 kJ/mol
D) +1512 kJ/mol
