Q. Choose the correct statement regarding the catalytic converters
A) Motor vehicles equipped with catalytic converter should use leaded petrol
B) Catalytic converters have expensive metals namely platinum-palladium and rhodium as catalyst
C) Catalytic converters help in reducing particulate matter
D) As the exhaust passes through the catalytic converter nitrogen gas is covered to nitric oxide
Explanation
Catalytic converters are filled into automobiles for reducing emission of poisonous gases like $NO_{2}$ and CO. They have expensive metals like platinum-palladium and rhodium as catalyst. As the exhaust emission passes through catalytic converter, nitric oxide splits into nitrogen and oxygen; carbon monoxide is oxidised to carbon dioxide and unburnt hydrocarbons get burnt completely into $CO_{2}$ and $H_{2}O$. Motor vehicles filled with catalytic converter should use unleaded petrol as leaded petrol inactivates the catalyst
