Q. In blast furnace, iron oxide is reduced by
A) Hot blast of air
B) Carbon monoxide
C) Carbon
D) Silica
Explanation
(b)
In the blast furnace, iron oxide is reduced by
$3{Fe}_{2}O_{3} + CO\ \overset{300 - 400℃}{\rightarrow}2{Fe}_{3}O_{4} + {CO}_{2}$
${Fe}_{3}O_{4} + CO\ \overset{500 - 600℃}{\rightarrow}3FeO + {CO}_{2}$
$FeO + CO\ \overset{700℃}{\rightarrow}Fe + {CO}_{2}$
