State all the necessary assumptions and calculate the entropy and Cp (in units of call per mole-deg) for HBr at 1 atm pressure and 200 C given that
here hω is the energy spacing between the ground and the first excited vibrational state in HBr in the ground vibrational and electronic states. The ground electronic state for HBr is nondegenerate.
