8.105 | 50. | Kudchadker S.A., 1978 | Recommended S(T) and Cp(T) values are in close agreement with statistical values calculated by [ Evans J.C., 1960, Green J.H.S., 1961]. Entropy value calculated by [ Sarin V.N., 1973] agrees well with the third-law entropy at 298.15 K but not at 400 K. Statistical values calculated by [ Ramaswamy V., 1970] seem to be erroneous.; GT |
