Carbon is more reactive than iron, so it can push out or displace the iron from iron oxide. Here are the equations for the reaction: iron oxide + carbon → iron + carbon dioxide. 2Fe 2 O 3 + 3C → 4Fe + 3CO 2. In this reaction, the iron oxide is reduced to iron, and the carbon is oxidised to carbon dioxide. In the blast furnace, it is so hot ...
