Homework Statement
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.
Homework Equations
dG=VdP-SdT+μdNi
The Attempt at a Solution
dG should decrease to be more stable.
d^2G should be positive so that there is a minimum G.
