15.3 This reaction (N2(g) + O2(g) = 2NO(g), also occurs when air (containing nitrogen and oxygen) is drawn into a car engine. The nitrogen monoxide (NO) thai forms is one of the exhaust gases that contributes to air pollution by forming smog and acid rain. 15.3.1 The gases in a car engine and exhaust systems reach extremely high temperatures. What effect will (a) the high temperature and (b) the addition of a catalyst have on the production of NO(g) and therefore the degree of pollution? Explain your answer using Le Chatelier's principle.
