Consult Chapter 12 of Vanderslice's text "Thermodynamics" for a simple
development of
dS = Q/T + Sum (si*dNi) for an open system.

Callen's Thermo text explicitly restricts the validity of Q=T*dS to
reversible, constant mole number, processes.

I read a nice article in J. Chem. Ed. yesterday. I simplified somewhat the
analysis in it and post my summary here:
I would be delighted by comments on it. (Try hard not to get hung up on
terminology, unless that *really* impedes understanding in your opinion.)
