Hydrogen burn inside a nitrogen atmosphere
« on: November 03, 2020, 01:29:43 AM »
What would happen if I had a hydrogen (H2) torch burning inside a container full of nitrogen (N2) and nitrous gas (NO2)?

Will the reaction create ammonia/ammonium? And if so, would the reaction be reversible at normal pressure?

No, the hydrogen react with die NO2   und form water and more nitrogen.
To get ammonia need high pressure see ammonia synthesis Bosch- Haber process.

Thanks for replying. Im aware of the haber-bosch process, I just wanted to know in what way my proposed synthesis will go wrong.

What about if I had a container full of H2 and N2 and applied a current in the form of an small electric arc?

Ammonia from an electric arc?

What would happen if I an electrical arc were to be made inside a container with a hydrogen (H2) and nitrogen (N2) atmosphere?

Will the reaction create ammonia/ammonium?

I combined your posts since they are asking similar question.

If you understand the thermodynamics behind the Haber-Bosch process, you will also understand that it is now an optimized process.
In an electric arc, you can break down ammonia into the elements with a nice yield.
see eg

ok, I made the other thread cause I wasn't getting an answer in this one

yes i understand that (it hasn't fundamentally evolved much since it was made. The reaction is reversible and, at low pressures, it highly favors the separation of ammonia into N and H). But, no hurt in trying to find other ways to synthesize ammonia. I also found another proposed process:
