Chemistry Question on Surface Chemistry
The adsorption of inert gases on the surface of activated charcoal increases with
A
decrease of both atomic mass and temperature
B
increase of both atomic mass and temperature
C
increase of atomic mass and decrease in temperature
D
decrease of atomic mass and increase in temperature
Answer
increase of atomic mass and decrease in temperature
Explanation
Solution
A gas having high atomic mass, will have greater intermolecular forces of attraction ahd hence cart be Iiquefied easily, The gas which is more easily Iiquefiable is more readily adsorbed. Adsorption increases with decrease of temperature.
