Liquid density and excess properties of argon + krypton and krypton + xenon binary liquid mixtures, and liquid density of ethane

Abstract

Experimental liquid densities of argon + krypton binary mixtures at 115.77 K, of krypton + xenon binary mixtures at 161.36 K, of one argon + xenon binary mixture at 115.77 K and of ethane at both 115.77 and 161.36 K were determined by the pyknometer method. Excess volume and excess Gibbs energy were obtained from the experimental data for argon + krypton and krypton + xenon binaries.
