Consider the following equilibrium in a closed container,
`N_(2)O_(4(g))hArr2NO_(2(g))`
At a fixed temperature, the volume of the reaction container is halved. For this change which of the following statements holds true regarding the equilibrium constant `(K_(p))` and degree of dissociation `(alpha)`?

A

Neither `K_(p)` nor `alpha` changes

B

Both `K_(p)` and `alpha` change

C

`K_(p)` changes but `alpha` does not change

D

`K_(p)` does not change but `alpha` changes

Text Solution

Verified by Experts

The correct Answer is:
D
The equilibrium constant depends only upon temperature. For endothermic reaction, the value of K increases with increase in temperature and vice-versa. The degree of dissociation must change to adjust for the new concentrations.
