The composition of the equilibrium mixture for the equilibrium C l 2 ⇌ 2 C l at 1470 K diffuses 1.16 times as fast as Krypton (84) under the same conditions. Find the degree of dissociation of C l 2 at equilibrium.

Options

  1. A0.14
  2. B0.41
  3. C0.91
  4. D0.24

Correct answer

A. 0.14

Step-by-step solution

C l 2 1 - x ⇌ 2 C l 2 x M m i x = ( 1 - x ) 71 + 2 x × 35.5 ( 1 - x ) + 2 x = 71 1 + x R m i x R K r = M K r M m i x 1.16 = 84 71 1 + x On solving x = 0.14
