Tor Fredrik Posted June 28, 2017 Author Share Posted June 28, 2017 I could come up with one reasoning: Can anyone come up with a bigger picture for why dS_sur is given by -dH/T? I know that dH=dU+pdv+Vdp=dQ-pdV+pdV+Vdp if dp=0 dH=dQ. The problem is why this Q is the Q of the surroundings? Link to comment Share on other sites More sharing options...
Tor Fredrik Posted June 29, 2017 Author Share Posted June 29, 2017 I believe I have made some progress: But in an equilibrium which I want to calculate with an ideal gas approximation. One uses standard chemical potential. Does anyone know how I can find the numerical value of the chemical potential for an ideal gas? Link to comment Share on other sites More sharing options...
