Catalytic converters have a large surface area to maximize the efficiency of the chemical reactions that convert harmful exhaust gases into less harmful emissions. The extensive surface area, typically achieved through a ceramic or metallic honeycomb structure, allows for more contact between the exhaust gases and the catalyst materials, enhancing the reaction rate. This design not only improves the converter's performance but also helps reduce the overall size of the unit while maintaining effective emissions control.

what is the surface area of a catalytic converter
Why are catalytic converters honeycomb shaped?
So the gases are in contact with a bigger area of catalyst
What provides a large surface area for gas exchange?
Your lungs provide a very large surface area for gas exchange.
Do stilts have a large surface area?
No
Why do leaves have a large surface area?
Leaves are broad, thin and flat to provide a large surface area, to absorb sunlight for photosynthesis. :)
Why does a small pin sink wheras a large boat does not?
Because a pin has a small surface area and a boat has a large surface area.
Name one organ in your body which has a large surface area?
The skin is an organ in the body that has a large surface area as it covers the entire external surface of the body.
What is in a catalytic converter?
A catalytic converter works by the various precious minerals and metals inside it. Quite simply they convert the dangerous chemicals inside the exhaust gases(carbon monixide,NOx etc) into less harmful ones (carbon dioxide etc). Due to the minerals and metals inside though they are often target to thieves as they can fetch quite a high price at the scrap yard. The catalytic converters that got stole off the HGV's at our work had a value of £800!Catalytic converters work by having the heated gases react with the precious metals in the catalytic converter. There is platinum palladium and rhodium in a catalytic converter all three are very expensive and rare metals. Because of the honeycomb shape of the catalytic biscuit there is a lot of surface area for the gas to be neutralized on.Prior to catalytic converters being on every car for every mile you drove your car would punch out somewhere around 100g's of pollution. After the addition of catalytic converters with platinum and palladium this number dropped to less than 1g of pollution per mile. After the addition of rhodium it dropped N/E which is non detectable.
What are the characteristics of respiratory surface?
large area
What stars are cool and bright stars?
To be bright you need to be hot, close or have a large surface area. The brightest coolest stars are red super giants. They have such a large surface area, that even though their surface temperature is cool - in star terms - their large surface area makes them appear bright.
Why do radiators have a large surface area?
Radiators have a large surface area to increase heat transfer efficiency. The greater surface area allows for more contact between the hot water or steam inside the radiator and the surrounding air, resulting in more effective heat dissipation into the room.
Why is it important that the gills of a crayfish give them a large surface area?
It is important that the gills of a crayfish give them a large surface area because it helps the crayfish to breathe. The bigger the surface area, the more oxygen in the crayfishes system.Ê
