Rossini 1938F. D. Rossini and R. S. Jessup, J. Res. Natl. Bur. Stand. 21, 491-513 (1938)
Heat and Free Energy of Formation of Carbon Dioxide, and of the Transition between Graphite and Diamond
note CO2cRossini 1938 re-evaluates the data of Jessup 1938 and Dewey 1938 and arrives at the weighted average enthalpy of combustion of graphite at 298.15 K to form 44.010 g of CO2 of -393355 +- 46 int. J/mol. Rossini 1940 restates the exact same result. This corresponds to -393418 +- 46 abs. J/mol, or for 44.0095 g of CO2 to 393.413 +- 46 abs. kJ/mol. This is slightly lower than our reinterpretation, see note CO2 and note CO2a, which produces a weighted average of 393.473 kJ/mol. Rossini also similarly analyses the combustion of diamond, arriving at -395254 - 115 int. J/mol. From these he derives the enthalpy for C -> C of 1899 +- 124 int. J/mol. Correcting this for the change in molecular weight of CO2 from 44.010 to 44.0095 and converting to abs. J/mol produces 1899.3 +- 124.0 abs. J/mol.
