For the equilibrium 2NOCl(g) ⇌ 2NO(g) + Cl 2 (g), the value of the equilibrium constant, K c is 3.75 × 10–6 at 1069 K. What is the value of K p for the reaction at this temperature?

Options

  1. AK p = 3.75 × 106
  2. BK p = 0.033
  3. CK p = 1069
  4. DK p = 2NOCl(g)

Correct answer

B. K p = 0.033

Step-by-step solution

We know that, K p = K c (RT) ∆n ,For the above reaction, ∆n = (2+1) – 2 = 1K p = 3.75 ×10–6 (0.0831 × 1069)K p = 0.033.
