In which of the following reactions, standard reaction entropy change (ΔS∘)\left(\Delta \mathrm{S}^{\circ}\right) is positive and standard Gibb's energy change (ΔG∘)\left(\Delta \mathrm{G}^{\circ}\right) decreases sharply with increasing temperature?
View answer and explanation
Correct option: C
C\mathrm{C} graphite +12O2(g)→CO(g)+\frac{1}{2} \mathrm{O}_2(\mathrm{g}) \rightarrow \mathrm{CO}(\mathrm{g})
Option C (C\mathrm{C} graphite +12O2(g)→CO(g)+\frac{1}{2} \mathrm{O}_2(\mathrm{g}) \rightarrow \mathrm{CO}(\mathrm{g})) is correct because the number of moles of gas increases (positive ΔS∘\Delta S^\circ) and increasing temperature favors the formation of products, thus decreasing ΔG∘\Delta G^\circ.
