Why does maximizing the surface area of the core increase the effectiveness of a catalytic converter

The answer is: Increasing the surface area of the core increases the chances of collision taking place.

Increasing the number of collisions per second increases the rate of reaction.

A catalytic converter has core, washcoat and catalyst.

Core is a ceramic or stainless steel honeycomb that supports the catalyst.

Usually converter is made from platinum, palladium or rhodium.

Reactions occur faster with a catalyst because they require less activation energy.

Catalytic converter splitts up the molecules after they leave a a mobile source (for example car's engine) and before they get released into the air.

It reduces emissions rather than eliminate them completely.
