Problem

Consider the following reactions at 1000°C. Zn(s)+12O2(g)→ΔZnO(g);ΔG∘=−360 kJ mol−1\text{Zn(s)} + \frac{1}{2}\text{O}_2\text{(g)} \xrightarrow{\Delta} \text{ZnO(g)}; \Delta G^\circ = -360\ \text{kJ mol}^{-1} C(s)+12O2(g)→ΔCO(g);ΔG∘=−460 kJ mol−1\text{C(s)} + \frac{1}{2}\text{O}_2\text{(g)} \xrightarrow{\Delta} \text{CO(g)}; \Delta G^\circ = -460\ \text{kJ mol}^{-1} and choose the correct statement at 1000°C. (1) ZnO is more stable than CO (2) ZnO can be reduced to Zn by C (3) ZnO and CO are formed at equal rate (4) ZnO can not be reduced to Zn by C
