Assuming that the system is composed of solid and liquid, it can be assumed that the immersion enthalpy

, thermodynamic studies at low concentration, of less than 0.05 mol kg −1 , are scarce; in the literature, data are found for partial molar volumes at molar concentrations above 0.05 mol L −1 [ 6 ] and it is only possible to find data of enthalpies of solution at

The standard molar enthalpies of formation of crystalline dialkyldithiocarbamates chelates, [Pd(S2CNR2)2], with R=C2H5, n-C3H7, n-C4H9 and i-C4H9, were determined through reaction-solution calorimetry in acetone, at 298.15 K. From the standard molar enthalpies of formation
of the gaseous chelates, the homolytic (172.43.8, 182.53.2,150.93.1 and 162.63.1 kJ mol−1) and heterolytic (745.03.8, 803.73.3,834.33.1 and 735.23.0 kJ mol−1) mean palladium-sulphur bond-dissociation enthalpies were calculated.
enthalpies of formation have also been measured by calorimetry, a universal technique widely used for the measurements of enthalpies of reaction, dissolution and excess enthalpies in thermochemistry. These data of the standard molar formation enthalpy plays

as the melting point and molar melting enthalpy of taurine were determined by Differential Scanning Calorimetry (DSC), the relation between the specific heat capacity and temperature was discussed, and the constant-volume combustion energies of the
The isothermal mixing of ( o + m ), ( o + p ), ( m + p )-isomers, which show small enthalpy change, can be explained in terms of differences in the intermolecular interaction between pairs of like and unlike
