Vedclass · Answer

(A) In a blast furnace,the reduction of iron oxides is primarily carried out by $CO$ gas,not by solid carbon $(C)$.Reaction $A$ $(2Fe_2O_3 + 3C \rightarrow 4Fe + 3CO_2)$ does not occur because solid carbon is not the primary reducing agent for $Fe_2O_3$ in the blast furnace; instead,$CO$ is used.Reaction $B$ $(CO_2 + C \rightarrow 2CO)$ occurs in the hotter zones.Reaction $C$ $(CaCO_3 \rightarrow CaO + CO_2)$ is the calcination of limestone.Reaction $D$ $(CaO + SiO_2 \rightarrow CaSiO_3)$ is the formation of slag.
