Critical temperature of SO2, N2, NH3 and...

Critical temperature of `SO_2, N_2, NH_3 and CH_4` are 430 K, 126K, 406 K and 356 K. Arrange in the descending order of volume of these gases adsorbed per gram of charcoal.

Text Solution

Verified by Experts

Extent of adsorption is directly proportional to critical temperature. Order of extent of adsorption of the given gases is: `SO_(2)gt NH_(3) gt CH_(4) gt N_(2)`.
