Assertion(A): Physical adsorption of mil...

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

A

If both (A) and (R) are correct, and (R) is the correct explanation of (A)

B

If both (A) and (R) are correct, but (R) is the correct explanation of (A).

C

If (A) is correct, but (R) is incorrect.

D

If (A) is incorrect, but (R) is correct. S

Text Solution

Verified by Experts

Activation energy is needed for chemical adsorption and not for physical adsorption. Breaking of bonds also takes place only in chemical adsorption.
