(a)
Interpretation:
The direction in which the equilibrium for the given reaction will shift with an increase in the volume of the container is to be predicted.
Concept Introduction:
Le-Chatelier principle states that the when a dynamic equilibrium is subjected to a change, the equilibrium moves in a direction so as to counteract that change. If the volume of the container increases, the pressure of the container decreases. The equilibrium will shift in the direction in order to decrease the pressure and vice versa.
(b)
Interpretation:
The direction in which the equilibrium for the given reaction will shift with an increase in the volume of the container is to be predicted.
