On the basis of a new model of chemical dissolution, an analysis of the kinetic parameters obtained using the modified Dolivo-Dobrovolsky equation was carried out. It shows that the change in parameters during the transition from one mineral to another is subject to a compensation effect. This means that there is a temperature point at which all minerals dissolve at the same rate. Therefore, at temperatures below that temperature, the reactivity of minerals settles in one sequence, and at temperatures above, in the opposite sequence. In addition, a new equation for the rate constant of chemical dissolution of minerals has been obtained. Calculations based on the new dissolution model made it possible to distinguish between the systemic and individual properties of minerals of the same nature in the process of dissolution. These minerals differ from each other by the concentration of active surface complexes, and are combined into a system by a single transmission coefficient and the same value of the lifetime of the active complex
