Chapter 16, Problem 16C.5P

Interpretation Introduction

Interpretation:

The given equation is a solution of diffusion equation has to be validated.

Concept introduction:

Diffusion of gas is a process in which the gas follows from higher pressure area to lower pressure area.  The process of diffusion requires a potential gradient.  The diffusion coefficient of a gas is given by the expression as shown below.

    $D=\frac{1}{3}\left(\frac{kT}{\sigma p}\right){\left(\frac{8RT}{\text{π}M}\right)}^{1/2}$
