Suppose now that there is no heat ow (dU = 0); however, the mass ow
dN exists between two parts of the system (Figure3.4). The temperatures of
these two sub-systems are equal T

potential to that with a lower chemical potential. Chemical potentials are
widely used to study whether a chemical reaction or a phase transition is
energetically protable.
