Consider the following reaction at\[1000{}^\circ C\]. (I) \[Zn(s)+\frac{1}{2}{{O}_{2}}(g)\xrightarrow{{}}ZnO(s);\]\[\Delta G{}^\circ =-360\,kJ\,mo{{l}^{-1}}\] (II) \[C\text{(graphite)}+\frac{1}{2}{{O}_{2}}(g)\xrightarrow{{}}CO(g);\]\[\Delta G{}^\circ =-\,460\,kJ\,mo{{l}^{-1}}\] Choose the correct statement at\[1000{}^\circ C\].

A)  Zinc can be oxidised by carbon monoxide

B)  Zinc oxide can be reduced by graphite

C)  Both statements a and b are true

D)  Both statements a and b are false

E)  Carbon monoxide can be reduced by zinc
