1-8-b Oxides of nitrogen
There are seven oxides of nitrogen that are present in the ambient air. These include nitric oxide (no),nitrogen dioxide (NO2) nitrous oxide (n2o),NO3 , N2O3, N2O4,and N2O5 [49].nitric oxide and nitrogen dioxide are collectively referred to as NOx due to their interconvertibility in photochemical smog reactions. The term NOy is often used to represent the sum of the reactive oxides of nitrogen and all other compounds that are atmospheric products of NOx . NOy includes compounds such as nitric acid (HNO3), nitrous acid (HNO2),nitrate radical (NO3), dinitrogen pentoxide (N2O5),and peroxyacetyl nitrate (PAN).It excludes nitrous oxide (N2O) and ammonia (NH3).while these latter two are often sources of NOx in the atmosphere,they are not normally the reaction products of NOx reactions.
