Two real gases have the same value of 'b' but the values of 'a' are different , molar volume of which of the gases will be less?

Two gases, obeying van der waals equation, have identical values of 'b' but different values of 'a'. Which one of the two gases will occupy less volume under identical conditions? If the values of 'a' for the two gases are the same but the values of 'b' are different, then under identical conditions which gas will be more compressible?

Four gases P, Q, R and S have almost same values of 'b' but their 'a' values (a,b are van der waals constants) are in the order Q lt R lt S lt P . At a particular temperature, among the four gases the most easily liquefiable one is-

Is the value of the coefficient of expansion of a gas the same for all gases?

The van der Waals Constants 'a' for different gases have been given as

What is molar volume ? Write its value at STP.

Two containers A and B have the same volume. Container A contains 5 moles of O_2 gas. Container B contains 3 moles of He and 2 moles of N_2 . Both the containers are separately kept in vacuum at the same temperature. Both the containers have very small orifices of the same area through which the gases leak out. Compare the rate of effusion of O_2 with that of He gas mixture.

Two different books have 3 volumes for each and three other different books have 2 volumes for each . In how many different ways can these 12 volumes be arranged on a shelf , so that the volumes of the same books may remain side by side ?

A gas mixture consists of three gases A, B and C with the number of moles 1,2 and 4, respectively.w hich of the gases will have a maximum partial pressure if the total pressure of the mixture is P at a given temperature ?
