Step 2:: Definition of Fick's Law
Fick's Law describes the diffusion of particles from an area of high concentration to an area of low concentration. It quantifies the rate of diffusion across a membrane or through a medium.
Step 3:: Fick's Law Equation
- $$\frac{dC}{dx}$$ = Concentration gradient (rate of change of concentration with respect to distance)
The one-dimensional form of Fick's Law is expressed as: Where: - The negative sign indicates diffusion occurs from high to low concentration
Step 4:: Variable Definitions
- $$x$$ (Distance): Measured in meters [m]
- D (Diffusion Coefficient): Measured in square meters per second [m^{2}/s]
Final Answer
Fick's Law describes diffusion as J = -D \frac{dC}{dx}, quantifying particle movement from high to low concentration regions.
