Question 12

During the industrial extraction of iron in a blast furnace, iron(III) oxide is heated with carbon monoxide gas to produce molten iron and carbon dioxide gas.

The chemical equation for this reaction is:

Fe2O3+3CO→2Fe+3CO2 \text{Fe}_2\text{O}_3 + 3\text{CO} \rightarrow 2\text{Fe} + 3\text{CO}_2 Fe2​O3​+3CO→2Fe+3CO2​

Explain, using this equation, which substance has been reduced in this reaction.
