The equilibrium SO2Cl2 (g) SO2 (g) + Cl2 (g) is attained at 25ºC in a closed container and an inert gas, helium is introduced. Which of the following statement is correct ? (PMT 2000)
A.More chlorine is formed
B.Concentration of SO2 is reduced
C.More SO2Cl2 is formed
D.Concentration of SO2Cl2, SO2 and Cl2 do not✓ Correct
Explanation
There is no effect on the equilibrium concentration by adding inert gas He at constant volume. Hence, there won’t be any change in the concentration of reactant or product.
