Vedclass · Answer

(B) According to Graham's Law of Diffusion,the rate of diffusion $r$ is inversely proportional to the square root of the molar mass $M$ $(r \propto \frac{1}{\sqrt{M}})$.For $NH_3$ $(M = 17 \ g/mol)$ and $HCl$ $(M = 36.5 \ g/mol)$,the rate of diffusion of $NH_3$ is higher than that of $HCl$ because $M_{NH_3} Since $NH_3$ diffuses faster,it travels a longer distance in the same amount of time.Therefore,the white $NH_4Cl$ ring will be formed closer to the $HCl$ bottle.

$A$ bottle of ammonia and a bottle of dry hydrogen chloride connected through a long tube are opened simultaneously at both ends. The white ammonium chloride ring first formed will be:
