Expalin the effect of temperature on the extent of physical and chemical adsorption .

Explanation

To explain the effect of temperature on the extent of physical and chemical adsorption, we can break down the concepts into clear steps:

### Step 1: Understanding Physical Adsorption
- Physical adsorption, or physisorption, is a type of adsorption that occurs due to weak van der Waals forces between the adsorbate and the adsorbent.
- It is generally characterized by low heat of adsorption (typically less than 20 kJ/mol) and is reversible.

### Step 2: Effect of Temperature on Physical Adsorption
- As the temperature increases, the kinetic energy of the molecules also increases.
