The device used to reduce gaseous emissions from a mobile source is the catalytic converter. Here's why:
1. Catalytic Converter: This device is installed in the exhaust system of vehicles to convert harmful gases such as carbon monoxide, nitrogen oxides, and hydrocarbons into less harmful substances like carbon dioxide and water vapor through chemical reactions.
2. Function: The catalytic converter contains a catalyst (usually platinum, palladium, and rhodium) that facilitates the conversion of toxic emissions into less harmful ones. This helps in reducing air pollution and meeting emission standards.
3. Impact: By using a catalytic converter, vehicles can significantly decrease their emissions of pollutants, thus contributing to cleaner air and reducing the environmental impact of transportation.
In summary, the catalytic converter is crucial for reducing gaseous emissions from mobile sources by converting harmful gases into less harmful substances through chemical reactions.
