H2 gas adsorbed an activated charcoal to a very little extent in comparison to easily liquifiable gases due to
Very strong Van der Waal interaction
Very weak Van der Waal interaction
Very low critical temperature
Very high critical temperature
As we learn
Application of adsorption -
Heterogeneous Catalysis
- wherein
Adsorption of reactant on the solid surface of the catalysts increases the rate of reaction. E.g. manufacture of ammonia using iron as catalyst.
