The balanced chemical equation for the reduction of iron(III) oxide using carbon monoxide in a blast furnace is:
Fe2O3+3CO→2Fe+3CO2 \text{Fe}_2\text{O}_3 + 3\text{CO} \rightarrow 2\text{Fe} + 3\text{CO}_2 Fe2O3+3CO→2Fe+3CO2Calculate the percentage atom economy of this process to produce iron .
atom economy (%)=total formula mass of desired producttotal formula mass of all reactants or products×100 \text{atom economy (\%)} = \frac{\text{total formula mass of desired product}}{\text{total formula mass of all reactants or products}} \times 100 atom economy (%)=total formula mass of all reactants or productstotal formula mass of desired product×100Give your answer to 3 significant figures.
(Relative atomic masses, ArA_rAr: C=12\text{C} = 12C=12; O=16\text{O} = 16O=16; Fe=56\text{Fe} = 56Fe=56)
