Several groups of general chemistry lab students measured the equilibrium constant for the same chemical equilibrium. In comparing their results, they found that they had different values because the temperatures of the experiments were different. Everyone was disappointed by the inconsistency, except for Dexter when he realized the measurements were made at different measured temperatures: "My esteemed colleagues," he said, "together we have sufficient data to determine two additional thermodynamic parameters and show the lab instructor what we know!" What...
