At constant volume and temperature conditions, the rates of diffusion D_A​ and D_B​ of gases A and B having densities ρ_A​ and ρ_B​ are related by the expression: 

50 mL of hydrogen diffuses out through a small hole of a vessel, in 20 minutes. The time taken by 40 mL of oxygen to diffuse out is

Under what conditions will a pure sample of an ideal gas not only exhibit a pressure of 1 atm but also a concentration of 1 mole litre^-1?

(R = 0.082 litre atm mol^-1 deg^-1)

Which of the following indicates the value of gas constant

The kinetic theory of gases predicts that total kinetic energy of a gaseous assembly depends on

The densities of two gases are in the ratio of 1:16. The ratio of their rates of diffusion is:

The ratio among most probable velocity, mean velocity and root mean square velocity is given by:

If there unreactive gases having partial pressure P_A​,P_B​ and P_C​ and there moles are 1,2 and 3  respectively then their total pressure will be :

According to Graham's law, at a given temperature the ratio of the rates of diffusion ​r_A/r_B​​ of gases A and B is given by: (where p and M are pressures and molecular weights of gases A and B respectively)

What is the relationship between the average velocity (v), root mean square velocity (u) and most probable velocity (α)
