Einstein solids, finding most probable values for equilibrium

  1. Feb 12, 2009 #1
    1. The problem statement, all variables and given/known data
    Consider the interation of two einstein solids, A and B. A has NA particles and qA units of energy and B has NB and qB units of energy. find the most probable values of qA and qB when equilibrium is reached.

    2. Relevant equations

    3. The attempt at a solution
    I set up the multiplicity formula (omega)=(qA+qB+NA+NB-1)!/(qA+qB)!(NA+NB-1)!
    but is there something i have to do to account for equilibrium in some way? do i have to differentiate something to get the maximum? I don't know how to even set up the probability or if it would even make any sense without any numbers
