Question 12

The reduction of iron(III) oxide by carbon monoxide in a blast furnace is represented by the balanced chemical equation:

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​

In an industrial process, a reaction vessel is loaded with 0.45 mol0.45\text{ mol}0.45 mol of iron(III) oxide, Fe2O3\text{Fe}_2\text{O}_3Fe2​O3​, and 1.20 mol1.20\text{ mol}1.20 mol of carbon monoxide, CO\text{CO}CO.

Use the stoichiometric ratio from the equation to show that iron(III) oxide is the reactant in excess.
