Fick’s Second 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.
