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, Product Details of 7181-87-5
Rate constants and activation parameters have been determined for the reactions of the aromatic amines N-methylimidazole and N-methylbenzimidazole with methyl iodide in acetonitrile-methanol.The enthalpies of solution have also been determined for the relevant species in the same solvent mixtures.Activation enthalpies in acetonitrile and specific interaction enthalpies between the amine and methanol show a linear correlation with pKa values determined in water only over a narrowly defined type of structure.However, transition-state indices for the two reactions defined in terms of physical interaction energy, alphaphys and betaphys, show the behaviour anticipated by analogy with reactions of pyridine derivatives. (i.e., family-independent character).
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Product Details of 7181-87-5, you can also check out more blogs about7181-87-5
