Chapter 5, Problem 5.21P

Interpretation Introduction

Interpretation:

The diffusion coefficient for diffusion of copper into silver at 1200 K should be calculated.

Concept introduction:

The diffusion coefficient is determined by using equation:

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

Here, $D_0$ is a temperature independent pre-exponential, $Q$ is the activation energy, $R$ is the gas constant and $T$ is the absolute temperature.
