Question

The ratio of rate of diffusion of helium and methane under identical condition of pressure and temperature will be

Answer 1

Rate of diffusion of helium and methane:

$\frac{Y_{He}}{Y_CH_{4}}=\sqrt{\frac{M_CH_{4}}{M_{He}}}$

Here,

${Y_{CH_{4}}=Rate of diffusion of CH_{4}$

${Y_{He}}=Rate of diffusion of He$

${M_{CH_{4}}=Mass of CH_{4}=16$

${M_{He}}$=Mass  of He=4

Putting the values in the above equation

$\frac{Y_{He}}{Y_CH_{4}}=\sqrt{\frac{16}{4}}$

                                             =2

Rate of diffusion of helium and methane is 2.
