NH_(3) ,CO_(2) are readily adsorbed where as H_(2), N_(2)are slowly adsorbed. Give reason.

Answer»

Solution :• The nature of adsorbate can influence the adsorption. Gases like `NH_(3) CO_(2)` are easily liquefiable as have greater van der Waals forces of ATTRACTION and HENCE readily adsorbed due to high critical temperature.
• But PERMANENT gases like `H_(2) ,N_(2)`can not be easily liquefied and having low critical temperature and adsorbed slowly.
