The isotherms of hydrogen, carbon monoxide and their mixtures

Abstract

In investigations involving gases at high pressures it is as essential to know the relative densities of the media concerned as it is their actual pressures. This demands a knowledge of the deviations from the ideal gas laws over wide ranges of pressure and temperature for each particular medium. Although reliable data are available for the commoner single gases, with perhaps the exception of carbon monoxide, as yet little is known concerning the compressibility of mixtures, except generally that neither the Law of Partial Pressures nor the Law of Additive Volumes is strictly obeyed. In this connection the recent researches of Masson, Verschoyle, Bartlett, Keyes and their co-workers have been very informative, yet a great deal more work needs to be done before such lacunæ in our knowledge of such matters are filled.
