The pseudo-first-order rate constant
WebbThe rate of the reaction is given by the expression rate =k[CH 3COOC 2H 5] Thus when one of the reactants is taken in large excess, a second order reaction will behave as a first order reaction. Such reactions are known as psuedo first order reactions. Video Explanation Solve any question of Chemical Kinetics with:- Patterns of problems > WebbThe chemical kinetics of a complex process could reduce to some pseudo-first-order or pseudo-second-order kinetics under some special operating conditions, but in such cases, the rate constants preserve their significance as those in the complex processes, i.e., the pseudo-rate constants remain closely related to the rate constant of the precursor …

WebbHowever, the estimated reaction rate constants assuming pseudo-1st order reaction agree with those reported based on batch studies. TCE degradation rate was proportional to concentration. This was considered to be the result of using high inflow concentrations of reactant, which might be the case at the vicinity of the source zones in aquifer. WebbIn biochemistry, Michaelis–Menten kinetics, named after Leonor Michaelis and Maud Menten, is the simplest case of enzyme kinetics, applied to enzyme-catalysed reactions of one substrate and one product.It takes the form of an equation describing the rate reaction rate (rate of formation of product P, with concentration ) to , the concentration of the …
