Why particles flow from high chemical potential to low

  1. Nov 10, 2013 #1
    1. The problem statement, all variables and given/known data
    Why does the equation (d2G/dNi2)T,P=(dμ/dNi)T,P>0 tells you that particles will flow from high chemical potential to region of low chemical potential at const. temperature and pressure?

    Thank you all.

    2. Relevant equations

    dG=VdP-SdT+μdNi


    3. The attempt at a solution

    dG should decrease to be more stable.
    d^2G should be positive so that there is a minimum G.
