Can internal energy levels of atoms affect chemical potential of ideal gas?

  1. Feb 25, 2012 #1
    μ/T represents the change in entropy if we change the number of particles,, so according to the fundamental assumption of statistical mechanics μ/T should tell us about the tendency of two systems to exchange particles...
    but I am having a hard time imagining how rotational or vibrational degrees of freedom (even if they increase entropy) can result in an exchange of particles.. the problem being that (unlike translational degrees of freedom) they don't have a tendency to push particles between systems.

    Am I missing something?

    Thanks for answering!!
