Question

At constant temperature, the equilibrium constant (K_p) for the decomposition reaction N₂O₄  ⇋ 2NO₂ is expressed by K_p = (4x²p/1 - x²)

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 increases with decrease of x

(D) K_p remains constant with change in P and x decreases with pressure

Answer 1

Correct option (D) K_p remains constant with change in P and x decreases with pressure

Explanation: 

K_p is a characteristic constant for a given reaction and changes only with temperature.
