At constant temperature, the equilibrium constant `(K_(P))` for the decomposition reaction. `N _(2)O_(4) hArr 2NO _(2)` is expressed by `K _(P) = 4x ^(2) P //(1 - x ^(2)) ` where, P is pressure, x is extent of decomposition. Which of the following statement 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 or x

Answer

D

Explanation

`K_(p)` is a characteristic constant for a given reaction and changes only with temperatures.
