Pressure against composition isotherms and thermodynamic data for the α-phase of the palladium/hydrogen system

Abstract

Pressure against composition isotherms have been determined for the α-phase of the palladium/hydrogen system in the temperature range 372–724 K, by direct equilibration with gaseous hydrogen. The partial molar enthalpy and partial molar entropy of solution of hydrogen in palladium have been derived as a function of composition. The values obtained at 600 K are, respectively, –15.56 kJ (mol H₂)^–1, and –96.5 JK^–1(mol H₂)^–1.
