S°gas | 480.18 | J/mol*K | N/A | Dworkin A., 1983 | The value of 428.1 J/mol*K was obtained for the third-law entropy value at 298.15 K if other enthalpy of sublimation of benzil was used. However, statistical values of S(298.15 K) calculated by author [ Dworkin A., 1983] for different molecular models (382.3 and 405.3 J/mol*K) are considerably less than the calorimetric values. |
