ABSTRACT
The heat capacity of Ru(C5H7O2)3 has been measured by the adiabatic method within the temperature range (6 to 310) K. The analysis of the functional dependence of the heat capacity has not revealed any thermal anomaly in its behavior. The thermodynamic functions (entropy, enthalpy, and reduced Gibbs free energy) at T = 298.15 K have been calculated using the obtained experimental heat capacity data. The obtained standard values are as follows: C p;m = (428.3 +- 0.2) J mol 1 K 1, D298:15 0 S m = (511.1 +- 0.5) J mol 1 K 1, D298:15 0 H m = (74.63 +- 0.05) kJ mol 1, U m = (260.8 +- 0.4) J mol 1 K 1.
