Identify the correct statement for the adsorption of areal gas on charcoal at 1 atm, 15^@C.

Answer»

Decrease in pressure increases the extent ofadsorption
Gases which are easily liquefiable, are adsorbed more in QUANTITY
Gases which have a behaviour similar to an inertgas are adsorbed more
None of these

Solution :The amount of gas adsorbed by a solid depends on the nature of gas. In general , more easily liquefiable gases (i.e., higher CRITICAL TEMPERATURE) are readily adsorbed as VAN der WAALS. forces are stronger near the critical temperature .
