The reduction of iron(III) oxide (Fe203) to pure iron during the first step of steelmaking,
2Fe2O3(s) ---> 4 Fe(s) + 302(g)
is driven by the high-temperature combustion of coke, a purified form of coal:
C(s)+ O2(g) --> CO2(g)
Suppose at the temperature of a blast furnace the Gibbs free energies of formation ΔGr of CO2 and Fe2O3 are-439. kJ/mol and-830. kJ/mol, respectively. Calculate the minimum mass of coke needed to produce 850. t of pure iron. (One metric ton, symbol t, equals 1000 kg.)
