In a blast furnace reduction process, 0.25 mol of iron(III) oxide, Fe2O3\text{Fe}_2\text{O}_3Fe2O3, is mixed with 0.80 mol of carbon monoxide, CO\text{CO}CO.
Fe2O3(s)+3CO(g)→2Fe(s)+3CO2(g) \text{Fe}_2\text{O}_3\text{(s)} + 3\text{CO(g)} \rightarrow 2\text{Fe(s)} + 3\text{CO}_2\text{(g)} Fe2O3(s)+3CO(g)→2Fe(s)+3CO2(g)Use the equation to show that, in this reaction, carbon monoxide is in excess.
