Which of the following defects are also called thermodynamic defects?

Since the oxidation state of oxygen is -2. So for 0.98 M has to be +2. Let the fraction of +3 M be x Then the fraction of 2+ M =(0.98-x) Now for the compound to be neutral 3x+2(0.98-x)=2 3x+1.96-2x=2 x=2-1.96 x=0.04 Fraction of +3 M is 4% Hence the correct option is option (b) 137. In Ag Br crystal, the ion size lies in the order Ag⁺ << Br–. The AgBr crystal should have the following characteristics (a) Defectless (perfect) crystal (b) Schottky defect only (c) Frenkel defect only (d) Both Schottky and Frenkel defects Schottky defect in AgBr is exhibited due to precipitation for both cations a
