Solution
The correct option is C the amount of Cl2 will have increased The equilibrium reaction is SO2Cl2(g)⇋SO2(g)+Cl2(g).
The forward reaction proceeds with an increase in the number of moles from 1 to 2. When the volume of the vessel is increased, the pressure decreases. The equilibrium will shift in the forward direction so as to nullify the effect of decreased pressure.
Hence, the amount of chlorine will have increased.
