Abstract: | A closed oscillation system comprised of alanine, KBrO3, H2SO4 and acetone catalyzed by tetraazamacrocyclic nickel(II) complex is introduced, and quantitatively characterized with kinetic parameters, namely the rate constant (k in, k p), the apparent activation energy (E in, E p) and pre-exponential constant (A in, A p) and thermodynamic functions (ΔH in, ΔG in, ΔS in and ΔH p, ΔG p, ΔS p), where indexes “in” and “p” mean “induction period” and “oscillation period,” respectively. The results indicate that tetraazamacrocyclic nickel(II) complex can catalyze alanine oscillating reaction and the reaction corresponds exactly to the feature of irreversible thermodynamics as the entropy of system is negative. |
