$ZnO + Mg 	o MgO + Zn$

Vedclass · Answer

(D) In an Ellingham diagram,a metal can reduce the oxide of another metal if the former's oxidation line lies below the latter's line at a given temperature. At $1100 \, ^oC$,the line for the formation of $MgO$ is significantly below the line for the formation of $ZnO$. Therefore,$Mg$ can effectively reduce $ZnO$ to $Zn$. The reaction $ZnO + Mg 	o MgO + Zn$ has the most negative Gibbs free energy change $(\Delta G)$ among the given options,making it the most spontaneous reaction.

The Ellingham diagram for zinc,magnesium,and carbon converting into corresponding oxides is shown below. At $1100 \, ^oC$,which reaction is spontaneous to a maximum extent?
