Cp,gas (cal/mol*K) Temperature (K) Reference Comment
40.131403.49Stromsoe E., 1970Ideal gas heat capacities are given by [ Stromsoe E., 1970] as a linear function Cp=f1*(a+bT). This expression approximates the experimental values with the average deviation of 1.42 J/mol*K. The accuracy of the experimental heat capacities [ Stromsoe E., 1970] is estimated as less than 0.3%.
