nanotube question

Hey,

Can someone please explain to me how to solve the question attached? The marking scheme talks about equilibrium between gaseous hydrogen and adsorbed hydrogen, but I didn't understand any of it.

Help would be really appreciated. :smile:

Absorbed h2 is in equilibrium with gaseous h2... Maybe try looking up absorption isotherms to supplement your knowledge.
As you lower the pressure of h2, hydrogen will (overall) desorb from the carbon as the pressure of h2 gas has dropped. This acts to maintain a near constant pressure of h2 in the container.
I'm sure you can state le chataliers principle!
