Write the reaction equation: N2-NH3-NO-NO2

The reaction between nitrogen and hydrogen takes place in the presence of catalysts, pressure, temperature 450 -5000 С.

N2 + 3H2 = 2NH3.

Ammonia burns to form nitric oxide (II) and water.

4NH3 + 5O2 = 4NO + 6H2O (occurs in the presence of catalysts).

Nitrogen oxide (II) NO is easily oxidized by atmospheric oxygen to nitrogen oxide (IV).

2NO + O2 = 2NO2.
