Q. At constant temperature, the equilibrium constant $(K_{p})$ for the decomposition reaction $N_{2}O_{4}(g) \rightleftharpoons 2NO_{2}(g)$ 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?
A) $K_{p}$ increases with increase of $p$
B) $K_{p}$ remains constant with change in $p$ and $x$
C) $K_{p}$ increases with increase of $x$
D) None of the above
Explanation
The correct answer is Option B: $K_{p}$ remains constant with change in $p$ and $x$.
