| 28.18 | 273.15 | Durig J.R., 1979 | It should be noted that values of S(T) and Cp(T) calculated by Durig et al. [ Durig J.R., 1980, Durig J.R., 1980, 2, Durig J.R., 1981] for alkenes are different from experimental ones and given in TRC Tables [ Thermodynamics Research Center, 1997] by 3-5 J/mol*K. So the accuracy of their data could exceed 2 J/mol*K. |
