Q. Identify the correct statement for the adsorption of a real gas on charcoal at 1 atm and 15$℃$
A) Gases which are small in molecular size are adsorbed more
B) Decrease in pressure increases the extent of adsorption
C) Gases which are easily liquefiable are adsorbed more in quantity
D) Gas which has a behaviour similar to an inert gas is adsorbed more
Explanation
(c)
Gases which have high critical temperature, have strong van der Waals’ forces of attraction and hence, are adsorbed to a greater extent.
