Shape Selective Catalysis By Zeolites

Explanation

### Step-by-Step Solution for Shape Selective Catalysis by Zeolites

1. **Understanding Shape Selective Catalysis**:
- Shape selective catalysis is a process where a catalyst selectively facilitates a reaction based on the size and shape of the reactants and products. This selectivity arises from the structure of the catalyst, which allows certain molecules to enter and react while excluding others.

2. **Combination of Catalysis and Molecular Sieve Effect**:
- This phenomenon combines two concepts: catalysis and the molecular sieve effect. The molecular sieve effect allows the catalyst to selectively absorb certain molecules based on their size, while catalysis refers to the acceleration of a chemical reaction.
