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 hold true regarding the equilibrium constant `(K_(p))` and degree of dissociation `(alpha)`?

Options

A. neither `K_(P)` nor `'alpha'` changes
B. both `K_(P)` and `'alpha'` changes
C. `K_(P)` changes but `'alpha'` does not
D. `K_(P)` does not change but `'alpha'` changes

Answer

D
