You are right in that the "total free energy" is used mainly due to
historical reasons. Be careful here though as explained in this thread:
As to Eq. 4, note not everybody agree with Klamt. For instance,
my view is that their Eq. 4. is not correct either and that the

is just a speculation, especially for D-PCM.
