Question

Name two metals used in a catalytic converter. How do they help in keeping the environment clean?

Answer 1

Cars are equipped with catalytic converters, which use costly metals like rhodium and platinum-palladium as catalysts, to lower the emissions of harmful gasses. Unburned hydrocarbons are transformed into carbon dioxide and water as the exhaust flows through the catalytic converter, while carbon monoxide and nitric oxide are transformed into carbon dioxide and nitrogen gas, respectively.
