Discrepancies with other statistically calculated values [ Green J.H.S., 1963] and [51KOB] increase at high temperatures up to 5 and 9 J/mol*K, respectively, in Cp(T).

Constant pressure heat capacity of gas

Cp,gas (cal/mol*K) Temperature (K) Reference Comment
24.632358.72Stromsoe 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 1.59 J/mol*K. The accuracy of the experimental heat capacities [ Stromsoe E., 1970] is estimated as less than 0.3%. Other experimental values of Cp [ Parks G.S., 1940] (118.83 at 427.9 K, 127.61 at 457.7 K, and 135.56 J/mol*K at 480.3 K) are believed to be less reliable.
