How do nitrogen oxides form
WebNitrogen oxides are released to the air from the exhaust of motor vehicles, the burning of coal, oil, or natural gas, and during processes such as arc welding, electroplating, engraving, and dynamite blasting. They are also produced commercially by reacting nitric acid with metals or cellulose. WebA natural source of nitrogen oxides occurs from a lightning stroke. The very high temperature in the vicinity of a lightning bolt causes the gases oxygen and nitrogen in the air to react to form nitric oxide. N 2 + O 2 --> NO. The nitric oxide very quickly reacts with more oxygen to form nitrogen dioxide. NO + O 2 --> NO 2.
