Nitrogen dioxide - Wikipedia. Nitrogen dioxide is a reddish-brown gas with a pungent, acrid odor above 21.2 °C (70.2 °F; 294.3 K) and becomes a yellowish-brown liquid below 21.2 °C (70.2 °F; 294.3 K). It forms an equilibrium with its dimer, dinitrogen tetroxide ( N2O4 ), and converts almost entirely to N2O4 below −11.2 °C (11.8 °F; 261.9 K). [6]. Nitrogen Dioxide | American Lung Association. Nitrogen dioxide, or NO 2, is a gaseous air pollutant composed of nitrogen and oxygen and is one of a group of related gases called nitrogen oxides, or NO x. Nitrogen dioxide forms when fossil fuels such as coal, oil, methane gas (natural gas) or diesel are burned at high temperatures.
