The lattice energy of \( \mathrm{NaCl} \) is \( 788 \mathrm{~kJ} \mathrm{~mol}^{-1} \). This
P means that \( 788 \mathrm{~kJ} \) of energy is required

W
(1) To separate one mole of solid \( \mathrm{NaCl} \) into one mole of \( \mathrm{Na}(\mathrm{g}) \) and one mole of \( \mathrm{Cl}_{(\mathrm{g})} \) to infinite distance
(2) To separate one mole of solid \( \mathrm{NaCl} \) into one mole of \( \mathrm{Na}_{(\mathrm{g})}^{+} \)and one mole of \( \mathrm{Cl}_{(\mathrm{g})}^{-} \) to infinite distance
(3) To convert one mole of solid \( \mathrm{NaCl} \) into one mole of gaseous \( \mathrm{NaCl} \)
(4) To convert one mole of gaseous \( \mathrm{NaCl} \) into one mole of solid \( \mathrm{NaCl} \)
