Question
For the diffusion of a gas at pressure P, the rate of diffusion is expressed by:
Options
A.r ∝ 
B.r = 
C.r ∝ 
D.r = 
Solution
According to Graham′s law of diffusion or effusion ″under simillar conditions of temperature and pressure, rate of diffusion is inversely proportional to square root of molecular weight″ rα
