Question

Assertion: Zeolites are shape selective catalysts.

Reason: The catalysing action of a zeolite depends upon the size of pores and cavities present in it.

Options

• If both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.

• If both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.

• If Assertion is correct but Reason is incorrect.

• If Assertion is incorrect but Reason is correct.

Answer 1

If both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.

Explanation:

Zeolites act as shape selective catalysts because their catalytic activity depends on the size and shape of their pores and cavities, which determine which molecules can enter and react. Thus, the size of the pores controls the catalysis, making the reason the correct explanation of the assertion.
