Calculate the ratio of the rate of diffusion of oxygen to the rate of diffusion of hydrogen at constant temperature and pressure.

The ratio of the rates of diffusion of helium with respect to methane under similar conditions of constant temperature and pressure is

The ratio of diffusion of hydrogen and helium gas is

What are the factors affecting the rate of diffusion?

What are the factors affecting the rate of diffusion.

The relative rates of diffusion of substances are

For the diffusion of a gas at pressure P, the rate of diffusion is expressed by

Indicate the correct answer: rate of diffusion of helium gas at constant temperature and pressure will be four times of the rate of diffusion of which of the following gases-

Find out the ratio of rate of diffusion of H_(2) and SO_(2) . (S = 32)

(i) Write down van der waals equation for 1 mol of a gas and hence deduce the equation for the same for n mol of the gas. (ii) Arrange CO_(2),SO_(2) and NO_(2) gases in increasing order of their rates of diffusion iunder the same condition of temperature and pressure wil reason.

Prove that at a certain pressure, the rate of diffusion of a gas is proportional to the square root of the absolute temperature of the gas.
