A molecule has three degenerate excited vibrational states, each with excitation energy above the ground state
a) At temperature T, what is the ratio between the number of molecules in (all of) these excited vibrational states and the number in the ground state?
b) At very high T, what is this ratio?
c) Assume you have N distinguishable molecules of this type. Use the free energy to compute the
entropy S/k of the system at temperature T.
d) Compute the number of microstates in the equilibrium macrostate at high temperatures and
explain why your answer makes sense.
