A+B⇌C+DA+B \rightleftharpoons C+D. If initially the concentration of AA and BB are both equal but at equilibrium, concentration of DD will be twice of that of AA, then what will be the equilibrium constant of reaction?A+B leftharpoons C+D . If initially the concentration of A and B are both equal but at equilibrium, concentration of D

Options

  1. A4/94 / 9
  2. B9/49 / 4
  3. C1/91 / 9
  4. D4

Correct answer

D. 4

Step-by-step solution

A+B leftharpoons C+D . If initially the concentration of A and B are both equal but at equilibrium, concentration of D Kc=[C][D][A][B]=2x×2xx×x=4K_c=\frac{[C][D]}{[A][B]}=\frac{2 x \times 2 x}{x \times x}=4
