Q. Among the reactions (a) - (d), the reaction(s) that does/do not occur in the blast furnace during the extraction of iron is /are :
$\left(a\right)\,CaO+SiO_{2} \rightarrow CaSiO_{3}$
$\left(b\right)\,3Fe_{2}O_{3}+CO \rightarrow 2Fe_{3}O_{4}+CO_{2}$
$\left(c\right)\, FeO+SiO_{2} \rightarrow FeSiO_{3}$
$\left(d\right)\, FeO \rightarrow Fe+\frac{1}{2}O_{2}$

Solution:

In blast furnace (metallugy of iron) involved reactions are
(a) $CaO + SiO _2 \longrightarrow CaSiO _3$
(b) $3 Fe _2 O _3+ CO \longrightarrow 2 Fe _3 O _4+ CO _2$
