Consider the following reactions at \( 1000^{\circ} \mathrm{C} \).
(I) \( \mathrm{Zn}(\mathrm{s})+1 / 2 \mathrm{O}_{2} \) (g) \( \stackrel{\Delta}{\longrightarrow} \mathrm{ZnO}(\mathrm{g}) ; \Delta G^{\circ}=-360 \mathrm{~kJ} \mathrm{~mol}^{-1} \)
(II) \( \mathrm{C}(\mathrm{s})+1 / 2 \mathrm{O}_{2}(\mathrm{~g}) \stackrel{\Delta}{\longrightarrow} \mathrm{CO}(\mathrm{g}) ; \quad \Delta G^{\circ}=-460 \mathrm{~kJ} \mathrm{~mol}^{-1} \)
and choose the correct statement at \( 1000^{\circ} \mathrm{C} \).
(a) \( \mathrm{ZnO} \) is more stable than \( \mathrm{CO} \)
(b) \( \mathrm{ZnO} \) can be reduced to \( \mathrm{Zn} \) by \( \mathrm{C} \)
(c) \( \mathrm{ZnO} \) and \( \mathrm{CO} \) are formed at equal rate
(d) \( \mathrm{ZnO} \) can not be reduced to \( \mathrm{Zn} \) by \( \mathrm{C} \)
