| Abstract: | The mathematical dependence of the enthalpy of formation on the average molar volumes of chemical compounds, the number of atoms in the formula unit and the temperature for the condensed state in the widest possible temperature range is obtained. It is established that in contrast to entropy and heat capacity, it is necessary to take into account the initial enthalpy of formation, which can be calculated by the additive scheme. For this the value of atomic enthalpies for all elements is calculated and it is shown that the proposed mathematical model in thisform allows to calculate the entropy of a compound with an average accuracy of up to 120 J/mol (R2-0.9). |
