Lola 4/5/2013 2:43:28 AM Apply Grahams law of effusion. it is:- rate(r) of effusion/diffusion is proportional to 1/ root [density(d) ] hecne r1/r2 = root( d2/d1 ) => r1/r2 = root ( M2/M1 ) since [2. vapour density(d)=molecular mass(M) ] now put rate=Volume/time=V/t all sums of this type are solved by this concept. Hope it gets cleared now.

Apply Grahams law of effusion.

it is:-

rate(r) of effusion/diffusion is proportional to 1/ root [density(d) ]

hecne r1/r2 = root( d2/d1 )

=> r1/r2 = root ( M2/M1 ) since [2. vapour density(d)=molecular mass(M) ]

now put rate=Volume/time=V/t

all sums of this type are solved by this concept.

Hope it gets cleared now.
