Abstract:

Partial pressures of C3g have been measured with a high-resolution mass spectrometer and a Knudsen effusion cell in the temperature range from 2300 to 2800K. The third-law heat of formation was derived with the thermodynamic functions of Strauss and Thiele as was the second-law value. The entropy values were also determined.
