When

r,p\,\,\mathrm{and}\,\,M

  represent rate of diffusion, pressure and molecular mass, respectively, then the ratio of the rates of diffusion

\left( {{r_A}/{r_B}} \right)

of two gases

A\,\,\mathrm{and}\,\,B

  is given as

View answer and explanation

Correct option: B

\left( {{p_A}/{p_B}} \right){\left( {{M_B}/{M_A}} \right)^{1/2}}

Option B (

\left( {{p_A}/{p_B}} \right){\left( {{M_B}/{M_A}} \right)^{1/2}}

) is correct because it represents the correct application of Graham's law of diffusion, incorporating both pressure and molar mass.
