Q. Consider the following reactions at $1100^{\circ} C$
(I)$ 2 C + O _{2} \longrightarrow 2 CO , \Delta G^{\circ}=-460 kJ mol ^{-1} $
(II) $ 2 Zn + O _{2} \longrightarrow 2 ZnO$
$\Delta G^{\circ}=-360 kJ mol ^{-1}$
Based on these, select correct alternate :

Solution:

$ZnO + C \rightarrow Zn + CO, \Delta G^{\circ} = -ve$.

Hence, this is spontaneous.
