THERMODYNAMIC PROPERTIES AS A FUNCTION OF TEMPERATURE L. V. Gurvich, V. S. Iorish, V. S. Yungman, and O. V. Dorofeeva The thermodynamic properties C ° p ( T ), S °( T ), H °( T )- H °( T r ), -[ G °( T )- H °( T r )]/ T and formation properties ∆ f ( T ), ∆ f ( T ), log K f °( T ) are tabulated as functions of temperature in the range 298 .15 to 1500 K for 80 substances in the standard state .The ref- erence temperature, T r , is equal to 298 .15 K . The standard state pressure is taken as 1 bar (100,000 Pa) . The tables are presented in the JANAF Thermochemical Tables format (Reference 2) . The numerical data are extracted from IVTANTHERMO databases except for C 2 H 4 O, C 3 H 6 O, C 6 H 6 , C 6 H 6 O, C 10 H 8 , and CH 5 N, which are based upon TRC Tables . See the references for information on standard states and other details . References 1 . Gurvich, L . V ., Veyts, I . V ., and Alcock, C .
