Introduction

Chemistry Open Book 2003 Describe, in terms of production of photochemical smog, what is meant by primary pollutants and secondary pollutants in the atmosphere, and list the main primary and secondary pollutants produced as a result of motor vehicles The combustion of fossil fuels in vehicles releases incompletely burnt chemicals and oxidised species known as primary pollutants into the atmosphere. ...read more.

Middle

The produces of these photochemical reactions are called secondary pollutants. Primary pollutants consist of oxides of nitrogen. In the atmosphere nitric acid, which is produced by high temperature combustion cylinders in engines, is oxidised to the brown gas nitrogen dioxide NO2, a major constituent to smog. N2(g) + O2 2NO(g) 2NO(g) ...read more.

Conclusion

smog, and how the high concentrations of tropospheric ozone are produced Describe the chemistry of the processes chosen as BPEOs at Longannet for minimising sulphur dioxide and NOx, emissions, and suggest why the Longannet management made those choices Outline the part played by chemists in the research on photochemical smog formation ...read more.
