Question

The volumes of gases H2, CH4, CO, and NH2
adsorbed by 1 gram of charcoal at 288 K are in the
order
(1) H2> CH4> CO > NH3
(2) CH4> co 2> NH3 > H2
(3) CO, > NH3> H2> CH4
(4) N3 > CO2 > CH4> H2​

Answer 1

--> The VOLUMES OF GASES H2, CH4, CO2 & NH3 ABSORBED by 1 gram of charcoal at 288k are in the ORDER :

NH3>CO2>CH4>H2

-->Firstly, We can find the ORDER OF VOLUME OF GASES ABSORBED BY 1 gram of CHARCOAL by knowing how easily a gas can be LIQUEFIED.

-->The easily LIQUEFIABLE GASES CAN BE ABSORBED TO A GREATER EXTENT.

SO, THE ORDER OF EASE OF LIQUIFIABILITY IS NH3>CO2>CH4>H2

and so is the ORDER OF VOLUME OF GASES ABSORBED BY 1gm of charcoal

Answer 2

Thus the order of gases is  NH3 > CO2 > CH4 > H2

Option (4) is correct.

Explanation:

The volume of gases H2, CH4, CO2 & NH3 absorbed by 1 gram of charcoal at 288 k are in the order:

NH3 > CO2  > CH4 > H2

First, we can find the order of volume of gases by 1 gram of charcoal by knowing how easily a gas can be liquefied.

The easily liquifiable gases can be absorbed to a greater extent.

Thus the order of gases is  NH3 > CO2 > CH4 > H2
