Write the chemical equation that represents the process of lattice energy for the case of nacl.

faust18 [17]

Answer: $Na^+(g)+Cl^-(g)\rightarrow NaCl(s),\Delta H_{Lattice}=-786kJ/mol$

Explanation:

Lattice energy : It is defined energy released when ions combine together in a gaseous phase to form a compound. it is energy possessed by the crystal lattice of a compound. Denoted by symbol $\Delta H_{Lattice}$ .
