Abstract
The vapour pressures of cadmium chloride, bromide, and iodide were measured by the Knudsen-effusion mass spectrometry, and are expressed by the equations: ln{p( CdCl 2 )/ Pa} = −(20030+220)( K/T)+(29.22±0.34),(560 to 700 K) , ln{p( CdBr 2 )/ Pa} = −(17110+410)( K/T)+(26.47±0.67),(560 to 670 K) , ln{p( CdI 2 )/ Pa} = −(16770+200)( K/T)+(29.47±0.37),(460 to 590 K) . The values of second- and third-law enthalpy and entropy of sublimation at 298.15 K have been calculated.
