The van der Waal equation of gas is (P+ (n^(2)a)/(V^(2))) (V - nb) =

1.	The van der Waal equation of gas is (P+ (n^(2)a)/(V^(2))) (V - nb) = nRT
Answer» (i) `CO_(2)` , (ii) `H_(2)` (i) `CH_(4)` , (ii) `CO_(2)` (i) `H_(2)` , (ii) `CO_(2)` `O_(2)`, (ii) `H_(2)` Solution :(i)Order of intermolecular attraction is `CO_(2)gt CH_(4)gt O_(2)gt H_(2)` In `CO_(2)`, intermolecular FORCES increases with number of electrons in a molecule. (ii)Size increases in order of `H_(2)LT O_(2)CH_(4)lt CO_(2)` Hence, `H_(2)` will have lowest VALUE of B.
