Question

Catalytic converter are fitted in to automobile to reduce emissions of harmful gases. Catalytic converter change unbent hydrocarbon into -

Answer 1

Typically there are two different catalysts in a catalytic converter;
A)one of them tackles nitrogen oxide pollution using a chemical reaction called reduction (removing oxygen).This breaks up nitrogen oxides into nitrogen and oxygen gases (which are harmless because they already exist in atmosphere around us).
B)the other catalyst work by an opposite reaction called oxidation(adding oxygen)and turns carbon monoxide into carbon dioxide. Another oxidation reaction turns unburned hydrocarbons in the exhaust to carbon dioxide and water.
