Question

how does hydrogen molecule reacts with CO and Co2​

Answer 1

Answer:

The Sabatier reaction or Sabatier process produces methane and water from a reaction of hydrogen with carbon dioxide at elevated temperatures (optimally 300–400 °C) and pressures (perhaps 30 bar) in the presence of a nickel catalyst.

Answer 2

How does Hydrogen molecule reacts with CO and CO₂ ?

​Hydrogen molecule reacts with carbon mono oxide in presence of different catalyst to give different products

$\begin{array}{l}3 \mathrm{H}_{2}+\mathrm{CO} \stackrel{\mathrm{Ni}}{\rightarrow} \mathrm{CH}_{4}+\mathrm{H}_{2} \mathrm{O} \\\\\mathrm{CO}+2 \mathrm{H}_{2} \stackrel{\mathrm{CuV} \mathrm{O}-\mathrm{Cr}_{2} \mathrm{O}_{3}}{\longrightarrow} \mathrm{CH}_{3} \mathrm{OH} \\\\\mathrm{CO}+\mathrm{H}_{2} \stackrel{\mathrm{Cu}}{\rightarrow} \mathrm{HCHO}\end{array}$

Hydrogen reacts with carbon dioxide at high temperature (300- 400 o C)  & high pressure  in presence of Ni  to give methane & water.

$\mathrm{CO}_{2}+4 \mathrm{H}_{2} \underset{\text { pressure }}{\stackrel{400^{\circ} \mathrm{C}}{\longrightarrow}} \mathrm{CH}_{4}+2 \mathrm{H}_{2} \mathrm{O}$
