Question:
Identify the reaction which occurs in blast furnace at temperature of above 900 K.
Identify the reaction which occurs in blast furnace at temperature of above 900 K.
Show Hint
Remember: At temperatures above 900 K in the blast furnace, $FeO$ is the predominant oxide being reduced.

- $3Fe_2O_3 + CO \rightarrow 2Fe_3O_4 + CO_2$
- $Fe_3O_4 + 4CO \rightarrow 3Fe + 4CO_2$
- $FeO + CO \rightarrow Fe + CO_2$
- $Fe_2O_3 + CO \rightarrow 2FeO + CO_2$

The Correct Option is C
Solution and Explanation
In a blast furnace, the reduction of iron oxide takes place in stages. At temperatures above 900 K, iron(II) oxide ($FeO$) is reduced by carbon monoxide to iron metal. This corresponds to the third reaction.
