Question

The reaction taking place in zeolites depends upon:

• A. size of reactant
• B. shape of reactant
• C. product molecules
• D. pores of zeolites

Answer 1

Answer: (A), (B), (C), (D)

The correct options are
A shape of reactant
B product molecules
C size of reactant
D pores of zeolites

Option $\left(A\right),\left(B\right),\left(C\right),\left(D\right)$ are correct.

The reactions taking place in zeolites depend upon the size and shape of reactant and product molecules as well as upon the pores and cavities of the zeolites. That is why these types of reactions are called ‘shape-selective catalysis’ reactions.
