Question

What happens when dihydrogen reacts with: 

(i) Oxygen 

(ii) nitrogen 

(iii) Carbon monoxide

Answer 1

(i) When dihydrogen reacts with oxygen, it form water.

2H₂(g) + O₂(g) \(\overset{\Delta}{\rightarrow}\)2H₂O(l) Water

(ii) When dihydrogen reacts with nitrogen, it forms ammonia.

(iii) When dihydrogen reacts with carbon monoxide, it forms methanol.

CO (g) + 2N₂ (g) \(\underset{200\,atm}{\stackrel{700k}{\rightarrow}}\) CH₃OH (l)

ZnO, CrO₃ Methanol
