Chemical Thermodynamic Properties of Compounds of Sodium,Potassium and Rubidium:An Interim Tabulation of Selected Values.

摘要

Selected values are given for the thermochemical properties of the more common compounds of sodium and potassium. A more extensive set of selections is provided for rubidium compounds. The properties included,where data are available,are enthalpy of formation at O K and 298.15 K,delta Hf(O) and delta Hf(298),Gibbs energy of formation,entropy and heat capacity at 298.15 K,delta Gf(298), S(298) and Cp(298) and the enthalpy difference between O K and 298.15 K, H(298)-H(O). The values are consistent with the tables issued earlier in the NBS Technical Note 270series.
