Specific Anion Effects on the Kinetics of Iodination of Acetone
Specific ion effects on the kinetics of iodination of acetone in an acidic medium are investigated by UV/Vis spectrophotometry as a function of nature of the acid and temperature. The results indicate that the order of the reaction with respect to acetone is practically unaffected by the composition of the acid while the value of the mixed constant k₁K increases according to the sequence HBr<HCl<HClO₄<HF<H₂ SO₄<H₃PO₄ . The results are discussed in terms of the hydration free energy and size of...[Show more]
