Hello!.
Physisorption is non- specific in nature. It involves Waal’s interaction between adsorbate and adsorbent.
On increasing the temperature physisorption decreases.
Physisorption is reversible in nature.
In case of physisorption, enthalpy change is small.
Chemisorption is highly specific in nature as it involves chemical bond formation between adsorbate and adsorbent.
On increasing the temperature chemisorption increases.
Chemisorption is irreversible in nature
In case of chemisorption, enthalpy change is high.
Thankyou!
Hope it helps!
