उत्तर
The activity and selectivity of zeolites as catalysts are based on both their pore size and size of their cavities on the surface.
Explanation:
The activity and selectivity of zeolites as catalysts depend on both their pore size and the size of cavities on their surface. Zeolites have interconnected channels and cavities of molecular dimensions, which create shape-selective catalysis by allowing only certain-sized molecules to enter and react. This size-dependent access controls the catalytic activity and selectivity of zeolites.
