The image above represents diffusion gradient. To calculate diffusion gradient, four essential parameters are needed and these parameters are **Concentration of Metal A (C _{A}), Concentration of Metal B (C_{B}), Points of Metal A (x_{A})Â **andÂ

**Points of Metal B (x**

_{B}).**The formula for calculating diffusion gradient:**

dC/dx =Â ^{(CAÂ – CB)}/_{(xAÂ – xB)}

Where:

dC/dx = Diffusion Gradient

C_{A}Â = Concentration of Metal A

C_{B} = Concentrations of Metal B

x_{A}Â = Points of Metal A

x_{B} = Points of Metal B

Let’s solve an example;

Find the diffusion gradient when the concentration of metal A is 2, the concentration of metal B is 3, the points of metal A is 4 and the points of metal B is 6.

This implies that;

C_{A} = Concentration of Metal A = 2

C_{B} = Concentrations of Metal B = 3

x_{A} = Points of Metal A = 4

x_{B} = Points of Metal B = 6

dC/dx =Â ^{(CAÂ – CB)}/_{(xAÂ – xB)}

dC/dx =Â ^{(2 – 3)}/_{(4 – 6)}

So, dC/dx = ^{(-1)}/_{(-2)}

dC/dx = 0.5

Therefore, theÂ **diffusion gradientÂ **isÂ **0.5**
