(A) The reduction of $ZnO$ to $Zn$ is typically carried out at $1673 \, K$. From the Ellingham diagram,it is observed that above $1073 \, K$,the Gibbs free energy of formation of $CO$ from $C$ is lower than the Gibbs free energy of formation of $ZnO$. Therefore,$C$ can easily reduce $ZnO$ to $Zn$ at these temperatures. On the other hand,the Gibbs free energy of formation of $CO_2$ from $CO$ is always higher than the Gibbs free energy of formation of $ZnO$ in this temperature range. Thus,$CO$ cannot effectively reduce $ZnO$. Hence,$C$ is a better reducing agent than $CO$ for the reduction of $ZnO$.

Out of $C$ and $CO$,which is a better reducing agent for $ZnO$?
