Question
The reduction of iron(III) oxide (Fe,O3) to pure iron during the first step of steelmaking,
2 Fe,0,(s)
4 Fe(s) + 30, (g)
is driven by the high-temperature combustion of coke, a purified form of coal:
C(s) + 0,(g) → co, (3)
Suppose at the temperature of a blast furnace the Gibbs free energies of formation AG, of CO, and Fe,O, are -422. kJ/mol and - 808. kJ/mol, respectively.
Calculate the maximum mass of pure iron that can be produced by the combustion of 680. t of coke. (One metric ton, symbol t, equals 1000 kg.)
Round your answer to 2 significant digits.
