At constant temperature , the equilibrium constant `(K_P)` for the decomposition reaction
` N_2O_4 hArr 2NO_2, ` 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?

A

`K_(p)` increases with increase in p.

B

`K_(p)` increases with increase in x.

C

`K_(p)` increases with decrease in x.

D

`K_(p)` remains constant with change in p and x

Text Solution

Verified by Experts

The correct Answer is:
D
The equilibrium constant does not change at all with changes in concentrations, volume, pressure and presence of catalyst. It changes only with changes in temperature of the system.
For endothermic reaction, the value of K increases with increase in temperature and vice versa.
For exothermic reaction, the value of K decreases with increase in temperature and vice versa.
