Vedclass · Answer

(B) Highly electropositive metals (like $Na, K, Mg, Ca, Al$) have a very high affinity for oxygen.Their oxides are extremely stable,meaning the $\Delta G_f$ of these metal oxides is highly negative.Carbon reduction is not feasible because these metals react with carbon at high temperatures to form stable ionic carbides rather than being reduced to the free metal.Therefore,these metals are typically extracted by electrolytic reduction of their molten salts.

Highly electropositive metals cannot be commercially extracted by the carbon reduction process at high temperatures because these
