उत्तर
Physical adsorption of a gaseous species may change to chemical adsorption with increase in temperature.
Explanation:
On increasing temperature physisorption changes to chemisorption. As the temperature increases, energy of activation of adsorbate particles increases which leads to formation of chemical bond between adsorbate and adsorbent. Hence, physisorption transform into chemisorption.
