Q. In a vessel containing $S{O}_3$, $S{O}_2$ and $O_2$ at equilibrium helium gas is added at constant volume. The dissociation of $S{O}_3$:

1. Increases
2. Decreases
3. Remains constant
4. Unpredictable

Q. Consider the following reactions:
(i) $PC{l}_5\left(g\right)\rightleftharpoons PC{l}_3\left(g\right)+C{l}_2\left(g\right)$
(ii) $N_2{O}_4\left(g\right)\rightleftharpoons 2N{O}_2\left(g\right)$
