Synthetic fertilizer
It is a process developed by two scientists - Kristian Birkeland and Sam Eyde - to fix atmospheric nitrogen for the production of fertilizer.
The nitrogen oxide produced is then used in the production of nitric acid and eventually, the production of synthetic fertilizer.
First, nitrogen is fixed into nitrogen oxide:
[tex]N_2 + O_2 --- > 2NO[/tex]
Then, the NO is oxidized:
[tex]2NO + O_2 -- > 2NO_2[/tex]
The nitrous oxide produced is then dissolved in water to form nitric acid:
[tex]3NO_2 + H_2O --- > 2HNO_3 + NO[/tex]
