The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.7181-87-5, Name is 1,3-Dimethyl-1H-benzo[d]imidazol-3-ium iodide, molecular formula is C9H11IN2. In a Article,once mentioned of 7181-87-5, name: 1,3-Dimethyl-1H-benzo[d]imidazol-3-ium iodide
Accurate second-order rate constants were measured at 5 C intervals in the temperature range 20-60 C for the Menshutkin reaction of 1-methylbenzimidazole, 2-amino-1-methylbenzimidazole and N,N-dimethylaniline with iodomethane and iodoethane in methanol. In every case a good linearity in the Eyring plots was observed. Values for the activation enthalpy and entropy are reported. Analysis in terms of Exner’s redefinition of the reactivity-selectivity principle (RSP) identified the present reaction series as a case of strong anti-RSP for selectivity towards the substrate. This case is shown to represent an isoselective relationship with the isoselective temperature lower than the experimental temperatures (beta(is) = -52 C). The isokinetic relationship does not hold in the reaction series with a fixed substrate. These findings suggest an early transition state in the Menshutkin reaction of polyfunctional aromatic imines.
The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 7181-87-5 is helpful to your research., name: 1,3-Dimethyl-1H-benzo[d]imidazol-3-ium iodide
