According to the Graham's law of diffusion, the rates of diffusion of two gases are directly proportional to their partial pressures and inversely proportional to their molecular weights.

The expression for the relative rates of diffusion of two gases is

r

Here, r

A

and r

B

are the rates of diffusion of two gases A and B respectively,

P

A

and P

B

are their partial pressures and M

A

and M

B

are their molecular weights respectively.
