Thermodynamic functions of ScVO4 at temperatures from 0 to 350 K
Source abstract
Abstract
The heat capacity of ScVO4 has been determined by adiabatic calorimetry at temperatures from 14.52 to 347.13 K, and smoothed heat capacity data have been used to evaluate its thermodynamic functions (entropy, enthalpy increment, and reduced Gibbs energy). At 298.15 K, the thermodynamic functions of scandium orthovanadate are C 0 (298.15 K) = 110.5 ± 0.1 J/(mol K), S 0(298.15 K) = 110.9 ± 0.1 J/(mol K), H 0(298.15 K) − H 0(0) = 18.53 ± 0.01 kJ/mol, and Φ0(298.15 K) = −[G 0(298.15 K)/298.15] = 48.75 ± 0.12 J/(mol K). The calculated Gibbs energy of formation of scandium orthovanadate from its constituent elements is Δf G 0(ScVO4, 298.15 K) = −1644.0 ± 2.2 kJ/mol.
