Gas Phase Heat Capacity (Shomate Equation)

Cp° = A + B*t + C*t2 + D*t3 + E/t2
H° − H°298.15= A*t + B*t2/2 + C*t3/3 + D*t4/4 − E/t + F − H
S° = A*ln(t) + B*t + C*t2/2 + D*t3/3 − E/(2*t2) + G
    Cp = heat capacity (J/mol*K)
    H° = standard enthalpy (kJ/mol)
    S° = standard entropy (J/mol*K)
    t = temperature (K) / 1000.

Quantity Value Units Method Reference Comment
Tc372.3KN/ACubitt, Henderson, et al., 1987Uncertainty assigned by TRC = 0.37 K; Tc from H.Kopper, 1936-450
Quantity Value Units Method Reference Comment
Pc88.90barN/ACubitt, Henderson, et al., 1987Uncertainty assigned by TRC = 1.30 bar; VP difference from hydrogen sulphide measured to 248 K. Sample purity judged from constancy of vapour pressure while melting at the triple point

In addition to the Thermodynamics Research Center (TRC) data available from this site, much more physical and chemical property data is available from the following TRC products:
