Question

1 Arrange the following gases in the increasing order of b Give reason 02 CO H He ii Arrange the following gases in the decreasing order of magnitude of a Give reason CH4 0 H ns Molar volume occupied by the gas molecules size of the molecules and van der Waak constant b represents molar volume of the gas molecules Hence value of b increases in the following order TH H He O CO ii van der Waals constant a is the measure of magnitude of intermolecular attraction The magnitude of intermolecular attractions increases with increase in size of electron cloud in a molecule Hence for the given gases magnitude of a decreases in the following order CH4 O H Greater the size of electron cloud greater is the polarisability of the molecule and greater is the dispersion forces or London forces
