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

Kp increases with increases of p

B

Kp increases with increases of x

C

Kp increases with decreases of x

D

Kp remains constant with change in p and x

Text Solution

Verified by Experts

The correct Answer is:
D
`N_(2)O_(4) rarr 2NO_(2)`
`Kp = 4x^(2)p/1-x^(2)`
Kp is function of temperature only. Does not change with either P or x.
