At constant temperature, the equilibrium constant `(K_(p))` for the decomopsition reaction `N_(2)O_(4)hArr2NO_(2)` is expressed by `K_(p) = ((4x^(2)P))/((1-x^(2))`, where P = pressure, x = extent of decomposition. Which one 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 and x

Answer

D

Explanation

`K_(p)` (equilibrium constant) is independent of pressure and concentration.
