Strontium crystallizes in a fcc unit cell with edge length a . It contains 0 .2% Frenkel defect and another crystal of Sr contains 0 .1% Schottky defect. Density of solid with Frankel defect = d f and density with Schottky defect = d s , then

Options

  1. Ad f = d s
  2. Bd f > d s
  3. Cd f < d s
  4. Dd f = 2 d s

Correct answer

B. d f > d s

Step-by-step solution

No effect on density due to Frenkel defect but due to Schottky defect density of solid decrease
