I have a somewhat unique question here.

I know that Pd is a very good absorper of hydrogen. My question is, supposing you start with a given volume of Pd and a given volume of H or even H_2 and it is absorped by the Pd is it possible to calculate the pressure that the hydrogen is under while it is inside the lattice structure of the Pd?

Try rephrasing your question; you want to know something about hydrogen in palladium, but as stated, it's not clear just what.

I wish to know the pressure that the hydrogen is under when it is absorped by the palladium. A given volume of Pd will absorp a given amount of hydrogen. Since the volume of the Pd remains constant, there must be a pressure exerted on the hydrogen to keep it within. I wish to know how to calculate that pressure.

Wolf, et al. (1993) "Pressure-composition isotherms for palladium hydride." Phys. Rev. B. 48: 12415 - 12418.

You can start here and refine as needed.

Heh.
