Coke as reducing agent
WebStep 2 – More coke is added to the furnace and reduces the carbon dioxide into carbon monoxide, a good reducing agent. CO 2 (g) + C(s) → 2CO(g) Step 3 – iron(III) oxide is … WebWhen coke or coal is used to reduce a metal oxide, it gets oxidized to CO. And, when CO itself is the reducing agent, it is oxidized to CO2 . MO + C = M + CO ; MO + CO = M + CO2 Thermodynamically, CO2 is much more stable than CO, as evident from the vast difference in their standard heats of formation.
