Question

As the automobile exhaust passed through the catalytic converter

• A. All of the above
  
• B. Unburnt hydrocarbons are converted into carbon dioxide and water
  
• C. Nitric oxide are changed to nitrogen gas
• D. Carbon monoxide are changed to carbon dioxide
  

Answer 1

The correct option is A All of the above


Introduction to catalytic converter

A catalytic converter uses a catalyst to transform the harmful compounds emitted by automobile engines due to fuel combustion into relatively less toxic forms.



Working of catalytic converter

Platinum-palladium and rhodium catalysts present in the converters help in oxidising and converting toxic by-products (formed due to unburnt hydrocarbons) into non-hazardous substances.

For example:-

1. Unburnt hydrocarbons are converted to carbon dioxide and water.
2. Carbon monoxide is converted to carbon dioxide.
3. Nitric oxide is converted to nitrogen gas.

Final Answer

d. All of the above.
