Schottky defect lowers the density of ionic crystals while frenkel defects does not .

Account for the following: Schottky defect lowers the density of Ionic crystalswhile Frenkel defect does not.

Assertion (A) :KCl is more likely to show Schottky defect, while Lil is more likely to show Frenkel defect. Reason(R): Schottky defects is more likely in ionic solids in which cations and anions are of comparable size while Frenkel defect is more likely in which cations and anions have large differences in their ionic sizes.
