Question

Why chemical adsorption increases with increase in temperature

Answer 1

Answer:

Chemisorption involves activation energy. The initial increase in chemisorption is due to the fact that the heat supplied acts as activation energy and more and more molecules of adsorbate gain energy and possess energy greater than activation energy. Therefore, adsorption increases with increase in temperature.

Answer 2

Explanation:

if a chemosorption in enodthermic mode then only increasing temp will result in increase in adoption rate , because equilibrium constant k is directly proportional to temperature for endothermic reaction
