Question

Why oxides of highly reactive metals cannot
be reduced by carbon?​

Answer 1

Answer:

The oxides of high reactive metals are very stable and cannot be reduced by carbon . Because metals have more affinity towards oxygen than carbon.so carbon is unable to remove oxygen from these metals oxides and convert them into free metals.

Answer 2

Answer:

Oxides of highly reactive metals cannot be reduced by carbon because highly reactive metals themselves are  good reducing agents, so they can’t be reduced by  carbon.
