Problem
In iron production, iron(III) oxide is reduced with carbon according to the equation
2Fe2O3(s)+3C(s)→4Fe(l)+3CO2(g)
A blast furnace charge contains 75.0kg of Fe2O3 and 18.0kg of carbon. The furnace operates at conditions where all reactants and products remain in the condensed or gaseous phases indicated.
(a) Identify the limiting reactant for this charge, justifying your choice with quantitative reasoning.
(b) Calculate the mass of liquid iron that can be produced when the reaction goes to completion.
(c) Determine the mass of the excess reactant remaining after the reaction has finished.
(d) Compute the mass ratio mass of Femass of CO2 generated in the furnace under these conditions.
