Two van der Waals gases have the same value of 'b' but different 'a' values. Which of these would occupy greater volume under identical conditions? If the gases have the same 'a' value but different values of 'b' which would be more compressible ?

The value of b determines the sizo of gas molecules. Thus a gas having higher value of b will have greater volume.

adetermines the attractive forces b/w gas molecules .A gas having higher value of a will have more attractive forces and is thus more compressible.
