Which will be adsorbed more readily on the surface of charcoal and why`-NH_(3)` or `CO_(2)`?

Which is adsorbed in minium amount by the activated charcoal?

Which of the two, He and Ne , gets adsorbed on the surface of charcoal more readily and why?

Give reasons for the following observations : (a) A deal is formed at the meeting point of sea water and river water. (b) NH_(3) gas adsorbs more readily than N_(2) gas on the surface of charcoal. (c ) Powdered substances are more effective adsorbents.

Adsorption is a surface phenomenon and it differs feom adsorption which occurs throughout the body of the substance which absorbs. In physisorption, the attractive forces are mainly van der Waals' forces while in chemisorption actual bonding occurs between the particles of adsorbent and adsorbente. Generally, easily liquefying gases are adsorbed more easily on the surface of a solid as compared to teh gases whihc are liquefied with difficult. Adsorption increases with the increases in pressure and decreases as the temperature is increases. The ease with which the gases H_(2),CH_(4),CO_(2)and NH_(3) are adsorbed on the surface of charcoal is :

Which of the following is adsorbed greatly by activated charcoal?
