Iron (III) oxide may be reduced to pure iron either with carbon monoxide or with coke (pure carbon). Suppose that 150kg of ferric oxide are available. How many kilograms of carbon monoxide would be required to reduce the oxide? How many kilograms of coke would be needed? In each case, how many kilograms of pure iron would be produced?
The equations are:
Fe2O3 3CO --> 2Fe 3CO2
2Fe2O3 3C --> 4Fe 3CO2
