Question

Reactions in zeolite catalyst depend on

• A. Pores
• B. Apertures
• C. Size of cavities
• D. All of these

Answer 1

The correct option is D

All of these

The explanation for correct options:

Option (D): All of these

1. The pore structure of the catalyst, as well as the size of the reactant and product molecules, all influence the shape-selective catalysis.
2. Because of their honeycomb nature, zeolites are good shape selectors.
3. Zeolites are crystalline solids containing micropores that have well-defined three-dimensional structures.
4. Oxygen, silicon, and aluminum are the three components of zeolites' regular structural frameworks.
5. Tetrahedral coordination between the aluminum and silicon atoms is maintained by the shared oxygen atoms in the chemical structure of zeolites.
6. Zeolites-based ion-exchange beds are widely used in water filtration, water softening, and a wide range of other domestic and industrial applications.
7. They are commonly used to isolate molecules in the field of chemistry since only molecules of specified sizes and shapes may pass through them.
8. Depending on the size of the molecules in the reactants and products, as well as the size of the pores in the zeolites, reactions take different paths.
9. Hence, it is the correct option.

Therefore, Reactions in zeolite catalysts depend on pores, apertures, and the size of cavities.
