Consecutive reaction
WebIn consecutive reactions, the rate-determining step often determines the kinetics. In consecutive first order reactions, a steady state approximation can simplify the rate law. The activation energy for a reaction is experimentally determined through the Arrhenius equation and the Eyring equation. WebThe reactions in which the reactants are converted to products through one or more intermediate stages are called consecutive reactions. The overall reaction is a result of several consecutive steps. Every steps has its own reactant and rate constant. Kinetics of Consecutive Reactions.

WebHowever, ethylene can also undergo a combustion reaction: C2H4 + 3O2 k2 2CO2 + 2H2O. To select for the first reaction, the oxidation of ethylene takes place in the presence of a silver catalyst, which significantly increases k1 compared to k2.

These reaction features are illustrated in the following example. …
WebThis is an example of a consecutive reaction, which occurs in two steps, with the intermediate playing a role. Another piece of evidence for a composite mechanism is the detection of reaction intermediates. In such a case, a reaction scheme must be devised that will account for these intermediates. Sometimes an intermediate can be a fairly ... WebThe next level of complexity which we need to consider, that of consecutive reactions.

WebWe present the reaction systems with adjustable kinetics that have been developed, which are easy to handle and analyze. We show examples of how the selectivity of competitive-consecutive reactions can be controlled via local bubble wake structures. This is demonstrated for Taylor bubbles and bubbly flows under technical conditions.
