On the basic of data given below, predict which of the following gases shows least adsoprtion on a definite amount of charcoal ? {:("Gas", CO_(2), SO_(2), CH_(4), H_(2)), ("Critical temp/K", 304, 630, 190, 33):}

Answer»

`CO_(2)`
`SO _(2)`
`CH_(4)`
`H_(2)`

Solution :HIGHER the CRITICAL temperature, greater is the adsorption, `H_(2)` has lowest critical temperature and HENCE is least adsorbed.
