gas316.3J/mol*KN/ACocks A.T., 1971This value was calculated from experimental values of entropy for solid bicyclo[2.2.2]oct-2-ene and enthalpy of vaporization. Value of 323.0 J/mol*K was obtained from the study of kinetics of the addition of ethylene to 1,3-cyclohexadiene [ Huybrechts G., 1980]. Estimations by means of the group additivity are equal to 331.0 [ Huybrechts G., 1980] and 330.1 J/mol*K [ Van Mele B., 1986].; GT
