# 6.23 The choice of a reducing agent in a particular case depends on thermodynamic factor. How far do you agree with this statement? Support your opinion with two examples.

From the graph we can observe that, a mtal oxide can reduce the oxide of other metals,if the $\Delta_f G$ of the first oxide is more than the second oxide.
example- $Mg$ can reduce $ZnO$ to Zn but Zn cannot reduce $MgO$ because  $\Delta_f G$ of  $MgO$ from Mg is more negative.
