of diffuses through a porous partition in 60 seconds. Volume (in L) of diffuse under similar conditions in 30 seconds will be :
12.14
14.14
18.14
28.14
As we learnt in Graham’s law of diffusion -
where r is the rate of diffusion of gas and M is the molar mass.
So, the volume of and time = 60 seconds
Therefore, rate
And for Oxygen, we have time = 30 seconds. Thus,
