Homework Help: Probability of occupancy in energy level as T->0 or inf.

  1. Apr 24, 2010 #1
    an atom has 3 non-degenerate E levels, = 0, e, 2e

    What is the prob of occupancy of each energy level as T-> zero and infinty and why?

    for E=0
    I imagine that the prob for T->0, is 1 is one or approaching one as as the temp approaches absolute zero electrons occupy the lowest state
    as T->infinity, i thought at first that the prob would approach zero as i would think everything would be more likely to occupy higher levels.

    but then i think i read somewhere that as T->inf. the prob for each level is equal.

    for the others i thought to use boltzmann

    so for E=e.......prob = (1/kT)exp[-e/kT]
    E=2e.......prob = (1/2kT)exp[-2e/kT]

    but wouldn't this give the same answers?
