Question

The equilibrium $ SO_2Cl_2 \, ( g) \rightleftharpoons SO_2 \, ( g) + Cl_2 \, ( g) $ is attained at $ 25^{\circ}C$ in a closed container and an inert gas, helium is introduced. Which of the following statements are correct ?

• A. Concentration of $SO_2,Cl_2 \,$ and $\, SO_2CI_2$ change
• B. More chlorine is formed
• C. Concentration of $SO_2$ is reduced
• D. None of the above

Answer 1

Answer: (D)

$ SO_2Cl_2 \, ( g) \rightleftharpoons SO_2 \, ( g) + Cl_2 \, ( g) $ .
Adding inert gas at constant volume will not affect partial pressure of reactant or products, hence will not affect equilibrium amount o f either reactant or products.
