Question

Identify the reaction that takes place in the blast furnace at \(1570\,\mathrm{K}-2170\,\mathrm{K}\).

• A. \(\mathrm{FeO + CO \rightarrow Fe + CO_2}\)
• B. \(\mathrm{Fe_3O_4 + 4CO \rightarrow 3Fe + 4CO_2}\)
• C. \(\mathrm{Fe_2O_3 + CO \rightarrow 2FeO + CO_2}\)
• D. \(\mathrm{FeO + C \rightarrow Fe + CO}\)

Hint:

Reduction of iron oxides in a blast furnace occurs in stages: \[ \mathrm{Fe_2O_3} \rightarrow \mathrm{Fe_3O_4} \rightarrow \mathrm{FeO} \rightarrow \mathrm{Fe} \] At the highest temperature zone, carbon directly reduces \[ \boxed{\mathrm{FeO}} \] to iron.
