A bottle of dry

\mathrm{N}{\mathrm{H}_3}

and bottle of dry

\mathrm{HCl}

connected through a long tube are opened simultaneously at both ends, the white

\left( {\mathrm{N}{\mathrm{H}_4}\mathrm{Cl}} \right)

ring first formed will be:

View answer and explanation

Correct option: B

Near the

\mathrm{HCl}

bottle

Option B (Near the

\mathrm{HCl}

bottle) is correct because, according to Graham's Law of Diffusion, HCl diffuses slower than NH3 due to its higher molecular weight, so they will meet closer to the HCl source.

If for the gases, the critical temperatures are mentioned below i.e.

\begin{array}{cccccccccccccccccccc} {\underline {{\text{Gas}}} }&{\underline {\,{\text{Critical}}\,\,{\text{temperature}}} } \\ {\text{A}}&{{T_{{C_1}}}} \\ {\text{B}}&{{T_{{C_2}}}} \\ {\text{C}}&{{T_{{C_3}}}} \\ {\text{D}}&{{T_{{C_4}}}} \end{array}

{T_{{C_1}}} > {T_{{C_2}}} > {T_{{C_3}}} > {T_{{C_4}}}
