Calculating Molar Gibbs Function

  1. Apr 2, 2012 #1
    1. The problem statement, all variables and given/known data
    For this question I'm to calculate the molar Gibbs function, G-G0, at 2000K for BSi given that the bond distance is 1.905[itex]A^{\circ}[/itex], [itex]ω^{~}[/itex] = 772cm-1, the ground electronic state has a degeneracy of 4, and the lowest energy excited electronic state, 8000cm-1 above the ground state, also has a degeneracy of 4.


    2. Relevant equations
    Gibbs Function G = H-TS ............ (1)

    where H is enthalpy, T is temperature and S is entropy.


    G-G0 = -kT ln(Z) + nRT ............ (2)


    3. The attempt at a solution
    So since it's molar i'm assuming there's going to be a volume term somewhere (in calculating partition function) and V=0.02446m3.

    Do I need to work out all the individual contributions to the partition function, Z, then just simply plug them into (2) ?
