At constant temperature, the equilibrium constant (K_(p)) for the decomposition reaction, N_(2)O_(4)iff2NO is expressed by K_(p)=((4x^(2)P))/((1-x^(2))), where P = pressure, x = extent of decomposition. Which one of the following statements is true?

Answer»

`K_(p)` increases with increase of P
`K_(p)` increases with increase of x
`K_(p)` increases with DECREASE of x
`K_(p)` remains constant with change in P and x

Solution :`K_(p)` is temperature dependent only. By CHANGING P or x equilibrium shifts as per LE Chatelier.s principle, but after some time it establishes a new state of equilibrium at which `K_(p)` is MAINTAINED constant.
