Question
Why is zinc not extracted from zinc oxide through reduction using $CO?$
✓
Answer
The standard Gibbs free energy of formation of $ZnO$ from $Zn$ is lower than that of $CO_2$ from $CO$. Therefore, $CO$ cannot reduce $ZnO$ to $Zn$. Hence, $Zn$ is not extracted from $ZnO$ through reduction using $CO$.
