Text Solution

Verified by Experts
The correct answer is:
D

For the reaction

where ' a ' is initial mole of present in V litre and ' ' is its degree of dissociation,
Also,
On reducing the volume of container to , initial concentration of becomes . An increase in concentration leads to more dissociation of in order to have constant, a characteristic constant for a given reaction at a temperature.
