Gas Phase heat Capacity (Shomate Equation)
Cp° = A + B*t + C*t2 + D*t3 + E/t2H° − H°298.15= A*t + B*t2/2 + C*t3/3 + D*t4/4 − E/t + F − HS° = A*ln(t) + B*t + C*t2/2 + D*t3/3 − E/(2*t2) + G Cp = warm capacity (J/mol*K) H° = standard enthalpy (kJ/mol) S° = conventional entropy (J/mol*K) t = temperature (K) / 1000.
