Abstract

In this paper, we discuss a statistical mechanical theory for calculating the standard nonelectronic entropies \( S_T^0 \) and free energy functions \([(\!G^0_t - H^0_{298}\!)\!/\!T]\) of substances at high temperatures. These quantities are important and are often the only unknown data necessary for determining free energies of compounds, which is necessary for the calculation of chemical and phase equilibria. This lack of data is particularly significant at high temperatures that are important in the genesis of magmas and metamorphic rocks.
