Vedclass · Answer

(D) The separation of noble gases is based on the principle of selective adsorption on coconut charcoal at different temperatures.At $173 \ K$,$Ar$,$Kr$,and $Xe$ are adsorbed on the surface of the coconut charcoal.However,$He$ and $Ne$ have very low boiling points and weak van der Waals forces,so they are not adsorbed at this temperature.Therefore,the gases that remain in the gaseous phase are $He$ and $Ne$.

The noble gas mixture is cooled in a coconut charcoal bulb at $173 \ K$. The gases that are not adsorbed are
