Solution:
- Equimolar amounts of $\mathrm{NO}$ and $\mathrm{NO}{2}$ at $-30^{\circ} \mathrm{C}$ gives $\mathrm{N}{2} \mathrm{O}_{3}(l)$ which is a blue liquid.
$$ \mathrm{NO}(g)+\mathrm{NO}{2}(g) \stackrel{-30^{\circ} \mathrm{C}}{\longrightarrow} \underset{(\text { Blue })}{\mathrm{N}{2} \mathrm{O}_{3}(l)} $$
