ELectrochemical sensing problem

  1. Nov 21, 2007 #1
    Anyone knows how to derive Fick's law of diffusion:


    Given current density applied to electrochemical sensing:
    I= nAve

    where :
    m=number of electrons
    F=faraday constant
    v=speed of particles
    n=number of charge carriers/vol
    A= cross-sectional area of sensor(electrode)
    e=charge of an electron

    Please help, at least give a clue where to start and the procedings.
