At constant temperature, the equilibrium constant (K_p)for the decomposition reaction, N_2O_4 hArr 2NO_2 is expressed by K_p=4x^2P//(1-x^2) , where P = pressure and x = extent of decomposition. Which of the following statements is true?

Answer»

`K_p`increases with increase in P.
`K_p`increases with increase in X.
`K_p`increases with decrease in x.
`K_p` REMAINS constant with CHANGE in P and x.

Solution :The equilibrium constant does not change with change in concentration, volume, pressure and presence of a catalyst. It CHANGES only with change in temperature of the system.
