The catalyst for the reactions is, List-I List-II N 2 ( g ) + 3 H 2 ( g ) → 2 NH 3 ( g ) In Haber's process N 2 and H 2 are combined in 1 : 3 ratio at 200 atm pressure and high temperature 400 - 450 ° C . Fe 2 H 2 ( g ) + O 2 ( g ) → 2 H 2 O ( l ) On passing Oxygen over Hydrogen adsorbed platinum, it gives Water. Pt CO ( g ) + 3 H 2 ( g ) → CH 4 ( g ) + H 2 O ( g ) In presence of Ni , they undergo complete reduction to give methane. Ni CO ( g ) + 2 H 2 ( g ) → CH 3 OH ( g ) A Controlled reduction occurs when CO is treated with Zn - CrO 3 . Zn - Cr 2 O 3
