Vedclass · Answer

(D) . Noble gases can indeed be separated by selective adsorption on coconut charcoal at different temperatures due to differences in their van der Waals forces.$B$. Animal charcoal is a well-known adsorbent used to remove colored impurities from solutions.$C$. Heterogeneous catalysis involves the adsorption of reactants on the catalyst surface,which increases the local concentration and lowers the activation energy,thereby increasing the reaction rate.$D$. Silica gel and alumina gel are used as desiccants to remove moisture from the air,not to increase it. Therefore,this statement is incorrect.
