Assertion: Extraction of iron metal from iron oxide ore is carried out by heating with coke. Reason: The reaction, Fe O (s) Fe(s)+ O (g) → is a spontaneous process.

Iron is obtained from ferric oxide by heating a mixture of calcium carbonate and coke in a blast furnace. In the blast furnace, CO is formed which reduced ferric oxide to iron. The reaction is 2 3 2 Fe O +3CO 2Fe+3CO → . The reaction of decomposition of ferric oxide is not spontaneous. Therefore, the correct answer is option (c) if assertion is true but Reason is false.
