Interpretation:
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.
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
For a steady state diffusion, the diffusion flux,
Here, negative sign denotes that diffusion is down the concentration gradient and
Unsteady state diffusion depends on time which means that atoms are either accumulated or depleted from a region.
The concentration gradient is the driving force for diffusion.
