For the reaction p + q ⇌ r + s , initially concentrations of p and q are equal and at equilibrium the concentration of s will be twice of that of p. What will be the equilibrium constant for the reaction?

Options

  1. A2
  2. B4
  3. C1/4
  4. D8

Correct answer

B. 4

Step-by-step solution

p x + q x ⇌ r 2 x + s 2 x At equilibrium K c = [ r ] × [ s ] [ p ] × [ q ] K c = 2 x . 2 x x . x = 4 x 2 x 2 K c = 4
