Identify the reaction that does not take place in a blast furnace.
View answer and explanation
Correct option: C
2Fe2O3+3C→4Fe+3CO22\mathrm{F}{\mathrm{e}_2}{\mathrm{O}_3} + 3\mathrm{C} \to 4\mathrm{Fe} + 3\mathrm{C}{\mathrm{O}_2}
Option C (2Fe2O3+3C→4Fe+3CO22\mathrm{F}{\mathrm{e}_2}{\mathrm{O}_3} + 3\mathrm{C} \to 4\mathrm{Fe} + 3\mathrm{C}{\mathrm{O}_2}) is correct because the reduction of Fe2O3Fe_2O_3 primarily occurs via CO in the blast furnace, not directly with carbon.
