Calorimetric enthalpies of absorption and desorption of protium and deuterium by palladium
TB Flanagan, W Luo, JD Clewley - Journal of the Less Common Metals, 1991 - Elsevier
In this research enthalpies were measured calorimetrically for the reaction of gaseous
hydrogen (protium or deuterium) with palladium over a range of hydrogen contents from [H
(D)][Pd]= 0 to [H (D)][Pd]≈ 0.77 (at 298 K). A twin-cell, heat leak differential calorimeter was
employed for these measurements. Results for the hydride formation enthalpies are− 19.1 kJ
(mol H)− 1 and− 17.3 kJ (mol D)− 1 at 298 K. Enthalpies of essentially the same magnitudes,
ie±0.1 kJ, are obtained from the decomposition of these hydrides. Entropies were …
