In the metallurgy of iron, during smelting process, CO is main reducing agent at the upper of blast furnace, because: (1) It is less concentrated in upper atmosphere (2) The CO2 formed can be easily removed (3) In the lower atmosphere, there is no oxide to be reduced (4) The entropy change during CO/CO is negative
