An iron ore is reduced in a furnace in accordance with the following

equation:

Fez03 + 9 CO = 2 Fe + 3 CO2 + 6 CO

The necessary carbon monoxide is obtained by the combustion of coke at the bottom of the furnace. The coke contains 86% C, which 6% is absorbed by the reduced iron and 80% is burned to CO, no COz being formed in the combustion. Find:

1. The volume of CO necessary to reduce one metric ton of iron.
2. The vol. of air used in burning this amount of coke.
3. The vol. and percentage composition of the gases.
