Equilibrium Question 720

Question: At constant temperature, the equilibrium constant ( $ Kp $ ) for the decomposition reaction $ N_2O_4 \leftrightharpoons 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-

Options:

A) $ K_{P} $ increases with increase of p

B) $ K_{P} $ increases with increase of x

C) $ K_{P} $ increases with decrease of x

D) $ K_{P} $ 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.
