Question
Out of C and CO, which is a better reducing agent at the lower temperature range in the blast furnace to extract iron from the oxide ore?
Solution
Out of C and CO, CO is a better reducing agent at the lower temperature range because `triangleG_(CO,CO_2)< triangleG_(Fe,FeO) ` . So, CO will reduce FeO, and will itself be oxidized to CO2.
