Determine activation energy from data
WebSep 17, 2024 · This iodine is immediately consumed by the thiosulfate ions (S 2 O 3 2-) in a pathway described by reaction (6). As soon as all of the S2O3 2- ions are consumed, the excess iodine produced in (5) is free to react with starch, turning the solution blue (7). The amount of thiosulfate ions added tells us how much iodine had been produced in the ... WebJan 1, 2007 · In general, activation energies for enzyme-catalysed reactions are within the range of 25- 63 kJ mol -1. Thus, catalase is not only more efficient than inorganic catalysts such as iodide, but also an exceptionally efficient enzyme. A low value of activation energy implies high efficiency of molecular collisions to form products.
