Solid Phase Heat Capacity (Shomate Equation)

Go To: Top, References, Notes / Error Report

C_p° = 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 -D_fH°_f,298
S° = A*ln(t) + B*t + C*t²/2 + D*t³/3 - E/(2*t²) + G
C_p = heat capacity (J/mol*K)
H° = standard enthalpy (kJ/mol)
D_fH°_298.15 = enthalpy of formation at 298.15 K (kJ/mol)
S° = standard entropy (J/mol*K)
t = temperature (K) / 1000.
