Answer ALL parts.
(a) An atom has a non-degenerate electronic state 1000 cm-¹ above a non-
degenerate electronic ground state. Determine:
(i)
the electronic partition function q² at 1500 K;
(ii)
the relative population of the upper state at 1500 K;
(iii)
the mean electronic energy at 1500 K;
(iv)
(²) when T→∞.
Determine the atomic partition function q for 35Cl atoms confined in a
volume of 0.01 m³ at 1500 K, given that the 2P₁/2 electronic state is found
900 cm-1 above the 2P3/2 electronic ground state. Justify any assumptions
that you make.
For a monatomic perfect gas with a non-degenerate electronic ground
state show that at room temperature (s) = 3kT/2. State any assumptions
that you make.
