Because of presence of holes the lattice energy decreases.

Vedclass · Answer

(B) In a Schottky defect,an equal number of cations and anions are missing from their lattice sites to maintain electrical neutrality and stoichiometry. This creates vacancies,which causes the density of the crystal to decrease. Since the formation of these defects is an endothermic process,the lattice energy of the crystal actually increases,not decreases. Therefore,the statement that lattice energy decreases is incorrect. The defect does increase electrical conductivity due to the migration of ions into the vacant holes.
