Question- The NO molecule is a free radical, and the unpaired electron could be spin up (alpha) or spin down (beta). This means that the electronic ground state has two degenerate states. The first excited state also has two degenerate spin states, and is 121 cm-1 higher in energy than the ground state.

a) Calculate the electronic partition function at 298 K

b) Why would you expect the electronic motion to contribute to the internal energies, heat capacity, and entropy of the molecule at 298K

c) Calculate the electronic contribution to the heat capacity at 298K for NO, assuming that only the two states, separates by 121 cm-1 , are available.

Please illustrate work if possible thanks
