(1) HINT: AgBr shows both Schottky and Frenkel defects.
Explanation:
AgBr shows both Schottky as well as Frenkel defect. In AgBr, both Ag+ and Br- ions are absent from the lattice causing Schottky defect. However, Ag+ ions are mobile so they have a tendency to move aside the lattice and trapped in interstitial site hence, cause Frenkel defect.
