If two molecules ofA and Bhaving mass 100 amu and 64 amu respectively and rate of diffusion ofA is 12×10-3,then what will be the rate of diffusion ofB?

Options:

Answer:
A
Solution:

According to Graham's law of diffusion

Rate of diffusion r∝1d

Molecular weight M=2×vapour density

r1r2=V.D2V.D1

MA=1002 

MB=642 

rA=12×10-3 and rB=?

rArB=dBdA=V.DBV.DA

12×10-3rB=64/2100/2=64100=810

rB=12×10-3×108

=15×10-3
