Biological examples of ficks law
WebFick's law is used to measure the rate of diffusion. It states that: (The symbol α means 'proportional to') The larger the area and difference in concentration and the thinner the surface, the quicker the rate. So, for example, in the lung the surface area is made very large by the presence of many alveoli. WebExample: Steady-state diffusion (Application of Fick's 1st Law)Compute diffusive flux and mass flow of hydrogen through a palladium membrane.

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.
