Fick's first law of diffusion is given by the following equation: \[ J = -D \dfrac{dc}{dx} \label{1} \] where \(J\) is the flux and is defined by the number or particles that are moving past a given region divided by the area of that region multiplied by the time interval. The units of \(J\) are mol m -2 s-1.
