Chapter 24, Problem 24.36P

Interpretation Introduction

Interpretation:

The diffusion coefficient of ${\text{n-C}}_{\text{12}}{\text{H}}_{\text{26}}$ in mobile and stationary phases has to be calculated and reason why one of these diffusion coefficient is higher than other has to be explained.

Concept Introduction:

Deemter equation:

The Deemter equation is given as,

$\text{H}\approx \text{A+}\frac{\text{B}}{{\text{u}}_{\text{x}}}{\text{+Cu}}_{\text{x}}$

Where A is multiple paths

$\frac{\text{B}}{{\text{u}}_{\text{x}}}$ is Longitudinal diffusion

${\text{Cu}}_{\text{x}}$ is equilibration time
