The second stage of the ostwald process begins by oxidizing nitric oxide gas in oxygen gas to nitrogen dioxide gas. then, the resulting nitrogen dioxide gas is absorbed by waterto yielding nitric acid hno3(aq) and some nitric oxidegas. these reactions are often carried out at ~50ºc (323 k) and atmospheric pressure. write these two balanced chemical reactions.
