Thermodynamics can tell you only that a reaction should go because the products are more stable (have a lower free energy) than the reactants. Another way of saying this is that the reaction has a negative free energy change: DG is negative and therefor the reaction is spontaneous.

The thermochemical and kinetic study of the attack of “B” type carbonate fluorapatites (B-CO 3-Fap) by a (19% w/w P 2 O 5) acid solution was performed using microcalorimetry at a temperature range between 25 and 55 °C and a pH 0.6. The results were processed iteratively in order to get the kinetic constant and the enthalpy of dissolution reaction.
