Vedclass · Answer

(C) In the blast furnace,the reduction of iron oxides $(Fe_2O_3)$ occurs primarily by carbon monoxide $(CO)$ to form iron $(Fe)$ and carbon dioxide $(CO_2)$,represented by reaction $(i)$. Additionally,the removal of silica $(SiO_2)$ impurity as slag $(CaSiO_3)$ occurs via reaction $(iv)$,where calcium oxide $(CaO)$ acts as a flux. Reaction $(ii)$ is not a primary reaction in the blast furnace for iron extraction,and reaction $(iii)$ is not the main reduction mechanism compared to the $CO$ reduction. Therefore,the correct reactions are $(i)$ and $(iv)$.

The main reactions occurring in a blast furnace during the extraction of iron from haematite are $....$.
$(i)$ $Fe_2O_3 + 3CO \to 2Fe + 3CO_2$
$(ii)$ $FeO + SiO_2 \to FeSiO_3$
$(iii)$ $Fe_2O_3 + 3C \to 2Fe + 3CO$
$(iv)$ $CaO + SiO_2 \to CaSiO_3$
