Verified by Experts

The correct Answer is:
D
Physical and chemical adsorption resemble only in effect of surface area, is
(a) Force of attraction is more in case of chemical adsorption.
(c) Chemical adsorption depends on activation energy. Thus, initially increases then decreases, i.e. above temperature. While physical adsorption only decreases with the increase in temperature.
(e) Physical adsorption is multilayered while chemical adsorption is a single layer adsorption.
