One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Recommanded Product: 253-52-1, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 253-52-1, Name is Phthalazine, molecular formula is C8H6N2
Kinetic and equilibrium studies of reactions of N-heterocycles with dimeric and monomeric oxorhenium(v) complexes
Equilibrium constants have been evaluated for the reaction {MeReO(edt)}2 + 2 L ? 2 MeReO(edt)L, where edt is 1,2-ethanedithiolate and L is any of 13 N-donor heterocyclic ligands. The values of K range from 1.37(27)¡Á10-2 for pyrimidine to 1.95(6)106 for imidazole at 25 C in chloroform. A successful correlation of logK with log (Ka) of HL+ was realized except in the case of the 2-substituted ligands 2-picoline and quinoline, where steric effects make K smaller than expected from the proton basicity of L. The kinetics of the same reactions were studied; the rate law for the reaction in the forward direction is given by -d[{MeReO(edt)}2]/dt = {ka + kb[L]}[L] ¡Á [{MeReO(edt)}2]. Except for 2-picoline and quinoline, the major pathway is provided by the term that shows the quadratic dependence on [L]. Values of log (kb) also correlate with log K, and therefore necessarily with log (Ka).
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Recommanded Product: 253-52-1, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 253-52-1, in my other articles.
