Chapter 5, Problem 5.54P

Interpretation Introduction

Interpretation:

The concentration of nitrogen 1 mm from the surface after 10 hours of diffusion needs to be calculated.

Concept introduction:

The diffusion can be calculated from the Arrhenius equation as follows:

  $D=D_0\exp \left(\frac{-Q_0}{RT}\right)$

Here, $D_0$ is the temperature independent pre-exponent, $Q_0$ is the activation energy for diffusion, $R$ is the gas constant, and $T$ is the temperature.
