Why is desorption important for a substance to act as good catalyst?

Text Solution

Verified by Experts

Desorption is very important for a substance to act as a good catalyst since after the reaction, the products formed on the surface must be removed (desorbed) so as to create free surface again for other reactant molecules to approach the surface and react.
