NEET2023ChemistryGeneral Principles and Processes of Isolation of MetalsActual
The reaction that does NOT takes place in blast furnace between 900K and 1500K temperature range during the extraction of iron is:
Options
- ACaO + SiO 2 → CaSiO 3
- BFe 2 O 3 + CO → 2 FeO + CO 2
- CFeO + CO → Fe + CO 2
- DC + CO 2 → 2 CO
Correct answer
B. Fe 2 O 3 + CO → 2 FeO + CO 2
Step-by-step solution
Except Option B remaining all reactions will takes place in blast furnace during extraction of iron. Fe 2 O 3 + CO → 2 FeO + CO 2 This reaction takes place at 500   -   800   K . At this temperature, the iron ore is in a solid state and the carbon monoxide is a gas. The coke burns in the lower part of the furnace to produce carbon monoxide, which rises through the furnace and reacts with the iron ore in the upper part of the furnace.
