प्रश्न
Why do physisorption and chemisorption behave differently with rise in temperature?
Advertisements
उत्तर
Physisorption involves weak van der Waals forces which weaken with rise in temperature. The chemisorption involves formation of chemical bond involving activation energy and like any other chemical reaction is favoured by rise in temperature.
