### Gas Phase Heat Capacity (Shomate Equation)

C_{p}° = A + B*t + C*t^{2} + D*t^{3} +
E/t^{2}

H° − H°_{298.15}= A*t + B*t^{2}/2 +
C*t^{3}/3 + D*t^{4}/4 − E/t + F − H

S° = A*ln(t) + B*t + C*t^{2}/2 + D*t^{3}/3 −
E/(2*t^{2}) + G

C_{p} = heat capacity (J/mol*K)

H° = standard enthalpy (kJ/mol)

S° = standard entropy (J/mol*K)

t = temperature (K) / 1000.
