1.	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
Answer» Activation energy is needed for chemical adsorption and not for physical adsorption. Breaking of bonds also takes place only in chemical adsorption.
