Question

Out of NH3 and CO2, which will be adsorbed more readily on surface of charcoal? Why?

Answer 1

The amount of gas adsorbed depends upon the nature of gas.  A gas with a higher critical temperature i.e. a more easily liquefiable gas is adsorbed to a greater extent.  Critical temperature for ammonia is 406K while that for CO2 is 304 K. 
In terms of Van derWaal’s forces, the substance with higher VanderWaal’s forces of attraction is more easily adsorbed.  Ammonia molecules are hydrogen bonded to each other while carbondioxide molecules are held together by weak dipole-dipole interactions.
NH3 has higher critical temperature  and larger VanderWaal’s forces of attraction than CO2 and therefore it will be adsorbed more readily than CO2.

Answer 2

Heyaa!!

YOUR QUESTION ANSWER IS NH3


Because NH3 have higher temperature and it absorbed more readily on surface of charcoal as it is having greater intermolecular force of attraction
