A similar question was asked before, but the formatting of the answer made it unreadable. So, I am asking it again. I have a thermodynamic system with three states in the canonical ensemble. p1 = .8, p2 = .19 and p3 = .01 at T = 300K. What are the energies of E2 and E3 relative to the ground state? I'm not sure which, of many, equations I'm supposed to start with as this isn't in the text and I don't understand my notes.
