The terms with ~ all neutralize each other in consequence of the 
equation of state. 
We can now write for the expression found:

If j? = 0, this passes into

i.e. the expression (c) for S2, because then there is only one kind

Now we find for the relation of equilibrium (a) in consequence 
of ( ) and (d), as the function of the temperature (7, disappears:
