Using tables
Thermodynamic properties of mineral compounds

The tables are essentially used to calculate an equilibrium constant. If Table 1 of the gives Δ _f H° and S° of the 150 chemical species for which these data are best known, only the table on the form can be used to quickly calculate an equilibrium constant, with sufficient accuracy when you want to know qualitatively whether or not a reaction is possible. For greater accuracy, the heat capacities listed in . Finally, the can be used to calculate solubility products or equilibrium constants of reactions in solution at 25 ˚C, and to recover standard electrode potentials.
