Which one of the following reactions occurs during smelting in the reduction zone at lower temperature (in iron metallurgy)?

A

CaO + SiO2\longrightarrowCaSiO3 (slag)

B

Fe2O3 + 3C \longrightarrow 2Fe + CO

C

3Fe2O3 + CO\longrightarrow2Fe3O4 + CO2

D

CO2 + C \longrightarrow 2CO

Answer

3Fe2O3 + CO\longrightarrow2Fe3O4 + CO2

Explanation

Solution

At lower temperature following reactions occur in blast furnace.

3Fe2O3 + CO \longrightarrow 2Fe3O4 + CO2 ; Fe3O4 + CO \longrightarrow 3Fe + 4CO2 ; Fe2O3 + CO \longrightarrow 2FeO + CO2
