In a blast furnace, iron is obtained when iron(III) oxide reacts with carbon monoxide. The reaction is given below. $\text{Fe}_2\text{O}_3 + 3\text{CO} \rightarrow 2\text{Fe} + 3\text{CO}_2$ Which substance undergoes oxidation, and which substance undergoes reduction in this reaction?
- Aoxidised: CO, reduced: $\text{Fe}_2\text{O}_3$
- Boxidised: $\text{CO}_2$, reduced: Fe
- Coxidised: Fe, reduced: $\text{CO}_2$
- Doxidised: $\text{Fe}_2\text{O}_3$, reduced: CO
