$2O_{3(g)} \rightleftharpoons 3O_{2(g)}; \Delta H^o = -285 \ kJ$

Vedclass · Answer

(C) According to Le Chatelier's Principle:
$1$. Low pressure favours the direction with an increase in the number of moles of gas $(\Delta n_g > 0)$.
$2$. Low temperature favours the exothermic direction $(\Delta H < 0)$.
Evaluating the options:
- Option $A$: $\Delta n_g = 2 - 1 = 1$ (Endothermic). Favoured at high $P$ and high $T$.
- Option $B$: $\Delta n_g = 1 - 3 = -2$ (Exothermic). Favoured at high $P$ and low $T$.
- Option $C$: $\Delta n_g = 3 - 2 = 1$ (Exothermic). Favoured at low $P$ and low $T$.
- Option $D$: $\Delta n_g = 2 - 2 = 0$ (Exothermic). Pressure has no effect; favoured at low $T$.
Thus,option $C$ is the correct answer.

For which of the following reactions is product formation favoured at low pressure and low temperature?
