Which of the gases diffuses faster among `N_(2)`, `O_(2)` and `CH_(4)`? Why?

The ratio of rates of diffusion of SO_(2) , O_(2) and CH_(4) is

Which of the pairs of gases diffuse at a slower rate than CO_(2) ?

If the densities of methane and oxygen are in the ratio 1 : 2 , the ratio of rate diffusion of O_(2) and CH_(4) is respectively

The value of van der Waals constant a for the gases O_(2) , N_(2) , NH_(3) , and CH_(4) are 1.360 , 1.390 , 4.170 , and 2.253 L^(2) atm mol^(-2) , respectively. The gas which can most easily be liquefied is

The ratio of the rate of diffusion of a sample of N_(2)O_(4) partially dissociated in to NO_(2) to pure hydrogen was found to be 1:5 . Calculate the degree of dissociation of N_(2)O_(4) .

For real gases, van der Waals' equation is written as (P+(an^(2))/(V^(2))) (V-nb)= nRT where a and b are van der Waals' constants. Two sets of gases are: (I) O_(2), CO_(2), H_(2) and He(II) CH_(4), O_(2) and O_(2) and H_(2) The gases given in set I in increasing order of b and gases given in set II in decreasing order of a are arranged below. Select the correct order from the following:
