Question

A catalytic converter is used to:

1. Minimize harmful pollutants
2. Improve fuel economy
3. Make the vehicle quieter
4. Let you use cheaper gas by converting it into better-burning fuel

Answer 1

1. Minimize harmful pollutants. A catalytic converter in an automobile is used to minimize harmful pollutants emitted during the combustion of gasoline by utilizing catalytically active metals. It converts carbon-containing compounds to carbon dioxide and reduces nitrogen oxides to less harmful gases.

Step-by-step explanation:

Catalytic Converters in Automobiles

Catalytic converters are used in automobiles to minimize harmful pollutants emitted by burning gasoline in the engine. They work by utilizing a blend of catalytically active metals, such as platinum or rhodium, to catalyze chemical reactions that convert carbon-containing compounds to carbon dioxide (CO2) and nitrogen oxides (NOx) into less harmful gases like nitrogen (N2) and oxygen (O2). Therefore, option 1 is correct.

Catalytic converters do not directly affect fuel economy (option 2). Their primary function is to reduce harmful emissions rather than improving fuel efficiency. Similarly, they are not designed to make the vehicle quieter (option 3). Although they may contribute slightly to reducing exhaust noise, exhaust system components such as mufflers are primarily responsible for noise reduction. Moreover, catalytic converters do not convert cheaper gas into better-burning fuel (option 4). They focus on minimizing pollutants rather than altering the properties of the fuel used.
