Question 57

In the extraction of iron within a blast furnace, hematite (Fe2O3\text{Fe}_2\text{O}_3Fe2​O3​) reacts with carbon monoxide gas (CO\text{CO}CO) to produce molten iron and carbon dioxide:

Fe2O3(s)+3CO(g)→2Fe(l)+3CO2(g) \text{Fe}_2\text{O}_3\text{(s)} + 3\text{CO(g)} \rightarrow 2\text{Fe(l)} + 3\text{CO}_2\text{(g)} Fe2​O3​(s)+3CO(g)→2Fe(l)+3CO2​(g)

Identify, with reference to the transfer of oxygen, which reactant undergoes reduction during this process.
