One mole of SO ₃ was placed in a vessel of 1 ~L capacity at a certain temperature and the following equilibrium was established. 2 SO _ 3(g) 2 SO _ 2(g) + O _ 2(g) If 0.6 moles of SO ₂ were formed at equilibrium, K_c for the reaction will be

Options

  1. A0.036
  2. B0.45
  3. C0.54
  4. D0.675

Correct answer

D. 0.675

Step-by-step solution

K_c= [ SO ₂ ]^2 [ O ₂ ] [ SO ₃ ]^2 = (0.6)^2(0.3) (0.4)^2 =0.675
