Einstein Probability Model

  1. Dec 12, 2009 #1
    1. The problem statement, all variables and given/known data
    In the Einstein model of a particular solid, one quantum of vibrational energy
    is ΔE=0.050 eV. This means an energy equal to ΔE is needed to raise an oscillator from
    one energy level to the next highest level. Assume this solid is at room temperature. What
    is the probability that any particular oscillator will be found in its first excited state, relative
    to the probability of finding it in its ground state?


    2. Relevant equations



    3. The attempt at a solution
    I have no idea how to this

    How many atoms have a kinetic energy less than 0.05 eV? How many have a kinetic energy that's more than 0.05 eV but less than 0.10 eV? You can use the Maxwell-Boltzmann distribution to figure this out.
