Question

A bottle of dry 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: (A) at the centre of tube (B) near the hydrogen chloride bottle (C) near the ammonia bottle (D) throughout the length of the tube

Molecular mass of N H3=17 Moleclar mass of H C l=35.5 ∵ rate of diffusion propto √(1/M) ∴ N H3 will diffuse faster than H C l and hence ring will be formed first nearer to H C l bottle.

Q. A bottle of dry 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:

at the centre of tube

near the hydrogen chloride bottle

near the ammonia bottle

throughout the length of the tube

Molecular mass of $N H_{3} = 17$
Moleclar mass of $H Cl = 35.5$
$∵$ rate of diffusion $\propto \frac{1}{M}$
$∴ N H_{3}$ will diffuse faster than $H Cl$ and
hence ring will be formed first nearer to $H Cl$ bottle.

Molecular mass of NH3​=17 Moleclar mass of HCl=35.5 ∵ rate of diffusion ∝M1​​ ∴NH3​ will diffuse faster than HCl and hence ring will be formed first nearer to HCl bottle.

Molecular mass of $N H_{3} = 17$
Moleclar mass of $H Cl = 35.5$
$∵$ rate of diffusion $\propto \frac{1}{M}$
$∴ N H_{3}$ will diffuse faster than $H Cl$ and
hence ring will be formed first nearer to $H Cl$ bottle.
