WebFeb 12, 2024 · Fick’s First Law of Diffusion. 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. Fick's second law predicts how diffusion causes the concentration to change with respect to time. It is a partial differential equation which in one dimension reads: where • φ is the concentration in dimensions of [(amount of substance) length ], example mol/m ; φ = φ(x,t) is a function that depends on location x and time t
