Chemical and Ionic Equilibrium 1 Question 32
33. The equilibrium $\mathrm{SO}{2} \mathrm{Cl}{2}(g) \rightleftharpoons \mathrm{SO}{2}(g)+\mathrm{Cl}{2}(g)$ is attained at $25^{\circ} \mathrm{C}$ in a closed container and an inert gas, helium is introduced. Which of the following statements are correct?
$(1989,1 \mathrm{M})$
(a) Concentration of $\mathrm{SO}{2}, \mathrm{Cl}{2}$ and $\mathrm{SO}{2} \mathrm{Cl}{2}$ change
(b) More chlorine is formed
(c) Concentration of $\mathrm{SO}_{2}$ is reduced
(d) None of the above
Show Answer
Solution:
- $\mathrm{SO}{2} \mathrm{Cl}{2}(g) \rightleftharpoons \mathrm{SO}{2}(g)+\mathrm{Cl}{2}(g)$,
Adding inert gas at constant volume will not affect partial pressure of reactant or products, hence will not affect equilibrium amount of either reactant or products.
