Question

What is meant by shape selective catalysis? Explain.

Answer 1

The reaction which depends upon the pore structure of catalyst and the size of reactant and product molecules .

Answer 2

Answer:

A catalytic reaction which depends upon the product molecules and on the size of the reactant and the pore structure of the catalyst is called shape-selective catalysis. For example, catalysis by zeolites is a shape-selective catalysis. Thus, molecules having a pore size more than 260-740 pm cannot enter the zeolite and undergo the reaction.
