Thermodynamic properties of simple substances

ΔH°f,298 и ΔG°f,298 – are changes the standard enthalpy (heat of formation) and the Gibbs's free energy in the formation (index f - formation) of the substance from simple substances, that are thermodynamically stable at 101.325 kPa (1 atm) and specified temperature of 298 K. 298 и p,298 - the standard entropy values and isobaric heat capacity of substances at 298 K. Heat capacity [J/(mol·K)] at temperature T, in temperature range indicated in the table is expressed by the equation:
p = a + bT + cT2 + c'/T2
