On the basis of data given below predict which of the following gases shows least adsorption on a difinite 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.
