Equilibrium Question 261

Question: At constant temperature, the equilibrium constant (Kp) for the decomposition reaction $ N_2O_4 $ ⇌ $ 2NO_2 $ is expressed by $ K_{P}=\frac{(4x^{2}P)}{(1-x^{2})} $ , where $ P= $ pressure, $ x= $ extent of decomposition. Which one of the following statements is true [IIT Screening 2001]

Options:

A) Kp increases with increase of P

B) Kp increases with increase of x

C) Kp increases with decrease of x

D) Kp remains constant with change in P and x

Show Answer

Answer:

Correct Answer: D

Solution:

$ K_{p} $ (equilibrium constant) is independent of pressure and concentration.
