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.
