Find the ratio of rates of diffusion of ...

Find the ratio of rates of diffusion of hydrogen and oxygen.

Text Solution

Verified by Experts

Graham.s law for the diffusion of two gases is given as `(r_1)/(r_2) = sqrt((M_2)/(M_1))`
Substituting the molecular weights, 32 for 2 oxygen and 2 for hydrogen, we get the ratio of rates of diffusion of `H_2 : O_2 = sqrt(32//2) = 4:1`.
