Ammonia, NH3, is oxidized to form nitrogen oxide, NO. Does this release NO, or does it produce a solution?
Does the term "nitrogen oxide auto-oxidizes to nitrogen dioxide" mean that when nitrogen oxide is generated, it will turn to red nitrogen dioxide
inside the apparatus, or does it mean oxygen must be presented directly?
NH3 + Oxidizer = NO (g) ----------- NO2 (g)
or
NH3 + oxidizer = NO (g) NO + O2 = NO2

Moved to Beginnings. Please, this is extremely fundamental, if you had a true interest in this, I cannot understand why you wouldn't read around on
the subject - here in the forum, on the internet and in any basic inorg text book.
Oxygen must be present, according to:
2 NO + O2 --> 2 NO2
Then, to produce HNO3:
2 NO2 + H2O --> HNO3 + HNO2
3 HNO2 --> HNO3 + 2 NO + H2O
etc.
This is essentially the Ostwald process.

There are a number of threads on this here (outside beginnings), if you wish to pursue this practically.

There are books on the process of making ammonia from atmospheric nitrogen and making nitric acid in the forum library,
Reading those freely available downloadable books is FAR better than spamming the board (even in Beginnings) with this sort of question.
