For the reaction: 2 NO 2 g ⇌ 2 NO g + O 2 g , K C   =   1 . 8 × 10 - 6   at   184 o C ,   R   =   0 . 0831   kJ   K - 1   mol - 1 when,   K P and K C are compared at 184 o C it is found that:

Options

  1. AK P is less than K C
  2. BK P   = K C
  3. CK P is greater than K C
  4. DWhether K P is greater than, less than or equal to K C depends upon the total gas pressure.

Correct answer

C. K P is greater than K C

Step-by-step solution

The realation between different equilibrium constant is given as: K P =   K C ( RT ) Δn g Δn g = ∑ gaseous   moles   of   products - ∑ gaseousmolesofreactents Δn g = 2 + 1 - 2 = 1 K P = K C ( RT ) K P > K C
