| Abstract/Summary |
The construction and principle of the new-established isoperibol oxygen-bomb combustion calorimeter are described. The energy equivalent ( ε calor ) of the calorimeter has been determined from ten combustion experiments using about 0.7 g of NIST 39i benzoic acid with a certified mass energy of combustion, Δ c U = − (26434 ± 3) J g − 1 , under experimental conditions: ε calor = (13572 ± 2) J K − 1 . The constant-volume energy of combustion of the compound, endo-tricyclo[5.2.1.0 2 , 6 ]decane (C 10 H 16 ), has been determined to be Δ U c (C 10 H 16 , s) = − (6070 ± 3) kJ mol − 1 by means of the oxygen-bomb combustion calorimeter at T = (298.15 ± 0.001) K. The standard molar enthalpy of combustion of the sample has been calculated, Δ c H om (C 10 H 16 , s) = − (6060 ± 3) kJ mol − 1 , from the constant-volume combustion energy. From the Hess thermochemical cycle, the standard molar enthalpy of formation of the compound has been determined, Δ f H om (C 10 H 16 , s) = − (161 . 83 ± 3 . 55) kJ mol − 1.
