For an elementary step, there is a relationship between stoichiometry and rate law, as determined by the law of mass action. Almost all elementary steps are either unimolecular or bimolecular. For a unimolecular step the reaction rate is described by , where is a unimolecular rate constant. Since a reaction requires a change in molecular geometry, unimolecular rate constants cannot be larger than the frequency … WebJan 24, 2024 · A high association rate (e.g. 10 6 M -1 s -1) combined with an average dissociation rate (e.g. 10 -3 s -1) can give a 1 nanomolar equilibrium dissociation constant. Therefore, some care must be taken comparing equilibrium dissociation constants alone.

WebMay 20, 2010 · I think a catalyst *does* change the rate constant. If I remember right, a catalyst will lower the activation energy and the Arrenhius equation is: k = A*e^ (-Ea/RT) Based on the above formula, lowering the activation energy … WebFeb 1, 2024 · Here, plasticity is governed by deformation twinning, in which kinetics is tightly correlated with the loading rate. Over the investigated range of strain rates, a hardening-like effect is found to shift the onset of the structural bcc-to-hcp phase transformation to a high, almost constant stress during the ramp compression regime.
