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=pressure x= extent of decomposition. Which of the following statements is true?
A. `K_(p)` increases with increase of P.
B. `K_(p)` increases with increases of x.
C. `K_(p)` increase with decrease of x.
D.
`K_(p)`
remains constant with change in p and x
