utomobile engines increase air pollution by emitting nitrogen oxides (NO?)(NOx) and carbon monoxide (COCO) from exhaust pipes. Catalytic converters reduce exhaust pollution by catalyzing the conversion of pollutants into gaseous nitrogen, oxygen, and carbon dioxide. Complete and balance the chemical equations for each catalytic converter reaction. Phases are optional.

Carbon monoxide gas is oxidized to carbon dioxide gas.

equation:
CO(g)+O2(g)−→PtCO(g)+O2(g)→Pt
 
Nitrogen dioxide is reduced to nitrogen gas and oxygen gas.
 
equation:
NO2(g)−→−Rh
