Web24 mei 2015 · In short, the coordination number is usually a compromise between 18-electron rule and size of ligands. For example, V ( C O) X 6 should dimerize, giving c.n. of 7 to vanadium, but can't do so because of size constrains. Web1 jan. 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.
