Detailed Solution

Lane's process is used for manufacturing of dihydrogen. It involves two stages:

1) Oxidation Stage: Super-heated steam is passed through iron fillings, at 1023-1073 K temperature when dihydrogen is formed.

3Fe + 4H₂O $\to$ Fe₃O₄ + 4H₂

2) Reduction Stage: Iron is regenerated by reducing magnetic oxide with water gas (CO+H2) This reaction is called vivification.

Fe₃O₄ + 4H₂ $\to$ 3Fe + 4H₂O
Fe₃O₄ + 4CO $\to$ 3Fe + 4CO₂
