* Effect of temperature: Since physical adsorption is an exothermic process, it occurs more readily at lower temperatures and decreases with increase in temperature ( Le-Chatelier's Principle).
* Effect of temperature: Even though chemical adsorption is an exothermic process, it does not occurs slowly at lower temperature due to high kinetic energy barrier. Hence, like most chemical changes, the extent of chemisorption increases with increase in temperature up to certain limit and then after that it starts decreasing.
