Abstract
For pt. II see abstr. A60612 of 1974. From measurements of the anelastic relaxation and the solubility for hydrogen in palladium, a spinodal curve for the PdH system has been determined. The critical point exponent, beta s, for this spinodal, is within experimental error, the same as that of the coexistence curve and both are in agreement with predictions of mean-field theory. Comparison of the solubility data with the isotherm equation due to Lacher (based on a mean-field approximation) shows that the equation holds reasonably well for 0< rho< or= H/Pd= 0.3 and temperatures within+ or-10% of the critical temperature (rho c= 0.29, T c= 566K).
