In the extraction of iron, the reaction which occurs at 900-1500 K in blast furnace is
Show Hint
Remember the different temperature zones and reactions that occur in the blast furnace during iron extraction.
Updated On: May 2, 2025
- Fe$_2$O$_3$ + 3C → 2Fe + 3CO
- FeO + CO → Fe + CO$_2$
- 3Fe$_2$O$_3$ + CO → 2Fe$_3$O$_4$ + CO$_2$
- Fe$_3$O$_4$ + 4CO → 3Fe + 4CO$_2$
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
In the blast furnace, iron ore (Fe$_2$O$_3$) is reduced to iron in several steps.
At 900-1500 K, the following reaction occurs:
FeO + CO → Fe + CO$_2$
This is the reduction of FeO (wustite) by carbon monoxide to produce iron and carbon dioxide.
