(b) Approximate analysis of the first few energy levels of oxygen atoms yield energies and degeneracies as listed in the following table: Energy (eV) degeneracy Level-1 0.00 9 Level-2 1.97 5 Level-3 4.19 1 Level-4 9.15 5 Level-5 9.52 3 (i) For an equilibrium system of oxygen atoms, calculate the temperature at which the number of atoms occupying "Level-4" will be equal to the number in "Level- 3". [4] (ii) Estimate the fraction of the oxygen atoms that would occupy "Level-5" at the temperature you calculated in part (b)(i). [4] (iii) More accurate analysis shows that the 9 states constituting "Level-1" are not perfectly degenerate, but actually span a range of energies approximately 0.0 -0.3 eV. Explain whether accounting for this fact would significantly alter your answer to part (b)(ii), and comment on whether the alteration would increase or decrease the fraction compared to your calculation in (b)(ii).
