The driving force for diffusion is to be determined. Concept introduction: When any substance moves from the area of its high concentration to an area of its low concentration, diffusion takes place. It happens primarily in fluids (liquids and gases) as the particles in fluids move in random manner from one place to another. Diffusion can also occur in solids but as particles are tightly packed in it, diffusion is slowest in solids.

Chapter 5, Problem 5.1P

Interpretation Introduction

Interpretation:

The driving force for diffusion is to be determined.

Concept introduction:

Diffusion can also occur in solids but as particles are tightly packed in it, diffusion is slowest in solids.

Expert Solution & Answer

Answer to Problem 5.1P

The driving force for diffusion is concentration gradient.

Explanation of Solution

The driving force for diffusion is the concentration gradient often expressed as dC/dx with the units of (atoms/ ( length ) 3)length. It is the composition rate of non-uniform material with respect to the distance.

For a steady state diffusion, the diffusion flux, J does not depend on time and is written as

J=−DdC/dx

Here, negative sign denotes that diffusion is down the concentration gradient and D is the diffusion coefficient.

Unsteady state diffusion depends on time which means that atoms are either accumulated or depleted from a region.

Conclusion

The concentration gradient is the driving force for diffusion.
