Vedclass · Answer

(C) The reduction of metal oxides by carbon is possible only for metals that have a lower affinity for oxygen than carbon at a given temperature. Highly reactive metals like $Ca$ and $K$ have a very high affinity for oxygen,and their oxides ($CaO$ and $K_2O$) are thermodynamically very stable. Therefore,these oxides cannot be reduced by carbon to their respective metals.

Among the following groups of oxides,the group containing oxides that cannot be reduced by carbon to give the respective metals is
