Consider an element that reaches its first excited state by absorption of 379.0 nm light.
a) Determine the energy difference (kJ/mol) between the ground state and the first excited state.
b) If the degeneracies of the two states for the element are g*/go = 1, determine N*/N_0 at 2090 K
c) By what percentage does N*/N_0 change if the temperature is raised by 20 K?
d) What is N*/N_0 at 5970 K?
