| Abstract: | Thermodynamic values for PUO1.5 were assessed using an improved method for estimating fef ° 1.5 and new data for S°298 1.5. Based on the assessment, a value of ΔH°298, 1.5=–828 kJ/mol is recommended. Measurements of (CO) pressure over the nominal equilibrium 1.5+ 1.5+ C were performed between 1348 and 1923 K, yielding pressures between 0.644 and 11600 Pa. Second- and third-law analyses were used to obtain a value for ΔH°298 1.5=–93.3°3.3 kJ/mol. |
