At constant temperature, the equilibrium constant ( K p ) for the decomposition reaction N 2 O 4 ( g ) ⇌ 2 NO 2 ( g ) is expressed by K p = ( 4 x 2 P ) ( 1 - x 2 ) , where P = pressure, x = extent of decomposition. Which one of the following statements is true?

Question

At constant temperature, the equilibrium constant ( K p ) for the decomposition reaction N 2 O 4 ( g ) ⇌ 2 NO 2 ( g ) is expressed by K p = ( 4 x 2 P ) ( 1 - x 2 ) , where P = pressure, x = extent of decomposition. Which one of the following statements is true?, K p remains constant with change in P and x, K p increases with decrease of x, K p increases with increase of x, K p increases with increase of P

MARKS App · Accepted Answer

K p can be written as: K p = NO 2 2 N 2 O 4 With change of pressure, x will change in such a way that K p remains a constant.
