The electronic ground state of molecular oxygen is three-fold degenerate, and the first electronic excited state is two-fold degenerate and is located at an energy 15.72 x 10-20 J above the ground state. In a sample of O2(g), maintained at an equilibrium temperature of 298 K, what would be the ratio of the populations of O2 molecules in the first electronic excited state versus the electronic ground state?
