gas is adsorbed on activated charcoal to a very little extent in comparison to easily liquefiable gases due to ____________.
(i) very strong van der Waal’s interaction.
(ii) very weak van der Waals forces.
(iii) very low critical temperature.
(iv) very high critical temperature.
The answer is the option (ii, iii). Due to very low critical temperature, only limited amount of hydrogen is adsorbed.
