That is, it is exothermic while loading and endothermic while deloading, and heat balances exactly. I do not think previous studies could have demonstrated this so convincingly. That's the beauty of a microcalorimeter. When I wrote this previously Ed Storms cautioned me to add that not all chemical reactions are reversible. Combustion, for example, is not. You cannot run it backwards in an electrochemical cell. (You can in an algae cell doing photosynthesis! Ha, ha.) But the heat of formation of a hydride is reversible, which is fortunate for this experiment. You don't have to know exactly how highly loaded it is. You do not have to know exactly how much chemical heat it should produce, which may not even be in the chemistry reference books. You need only show a balance. Scott Little has nice calorimeters. Not micro-calorimeters, but accurate. He showed an elegant demonstration with a reversible chemical reaction: charging and discharging a rechargable battery. It was endothermic charging up, and exothermic discharging inside the cell through a Joule heater, and it balanced up nicely. - Jed
