What is a Washburn correction?
The Washburn correction consists of reduction or correction of the results of a calorimetric process to standard states. Correction is made for the following: • Compression of the condensed phase and gas phase species to 1 atm pressure • Enthalpy of solution and of dilution of the product gases in the aqueous phase (e.g. HCl, 1:600) • Vaporization of water because of the heat liberated by the reaction • Any energy changes associated with non-isothermal reactions More details on these corrections can be found on pages 72-74 of Cox, J.D.; Pilcher, G., Thermochemistry of Organic and Organometallic Compounds, Academic Press, New York, 1970.
