Assertion(A): Physical adsorption of molecules on the surface requires activation energy.
Reason(R): Because the bonds of adsorbed molecules are broken.

A

If both assertion and reason are ture, and reason is the trure explanation of the assertion.

B

If both assertion and reason are true, but reason is not the true explanation of the assertion.

C

If assertion is true, but reason is false.

D

If both assertion and reason false.

Text Solution

Verified by Experts

The correct Answer is:
D
Correct A. Activation energt is needed for chemical adsorption and not for physical adsorption.
Correct R. Breaking of bonds also takes place only on chemical adsorption.
