A pseudo first-order-second-order kinetics experiment: An illustration of the Guggenheim method
Journal of Chemical Education, 1964The rate of one of the typical reactions of the aromatic nitroso group is determined spectrophotometrically employing the Guggenheim method.

Simulation of 1,3-dichloropropene in topsoil with pseudo first-order kinetics
Journal of Contaminant Hydrology, 1995Abstract For fast-degraded chemicals such as 1,3-dichloropropane (1,3-D), their long persistent time in topsoils cannot be explained by the ordinary first-order kinetics of biodegradation that is commonly used in the simulation of chemical transport in soils.

A continuous spectrophotometric procedure is presented for the measurement of the kinetic properties of acetylcholinesterase (EC 3.1.1.7) with its natural substrate, acetylcholine. The procedure is based upon the production of stoichiometric quantities of H+ upon hydrolysis of substrate.

Enhanced Kinetics of Pseudo First-Order Hydrolysis in Liquid Phase Coexistent with Ice
The Journal of Physical Chemistry A, 2013The reaction rate of the hydrolysis of fluorescein diacetate (FDA) is several times larger in the frozen state than that in the unfrozen solution of the same composition at the same temperature. The freeze concentration of reactants in the liquid phase expelled form ice crystals cannot explain the kinetic enhancement of pseudo first order reactions ...

Iodipamide was infused into three dogs with bile fistulas to achieve various steady-state blood levels. When using ultracentrifugation techniques, iodipamide was found to be highly bound to plasma protein. The total blood clearance was low relative to hepatic blood flow.

Probenecid Disposition by Parallel Michaelis-Menten and Dose-Dependent Pseudo-First-Order Processes
Journal of Pharmaceutical Sciences, 1986Re-evaluation of published data on the urinary excretion of probenecid [4-(dipropylamino)sulfonylbenzoic acid, 1] and its metabolites as a function of orally administered dose has revealed that the elimination process is comprised of five parallel pathways.

The study of bimolecular reactions under non-pseudo-first order conditions
Biophysical Chemistry, 2005In this work a new equation which describes the time evolution of bimolecular reactions is derived and tested by experiment. The equation is general and the results show that second-order reactions of any simple type may be accurately described by a quotient of exponential functions. The model and reagent concentration dependent observed rate constants

Fitting isoperibolic calorimeter data for reactions with pseudo-first order chemical kinetics
Journal of Thermal Analysis and Calorimetry, 2005The non-linear least squares fitting of the chemical heat flow and the reactor temperature are compared for reactions with pseudo-first order chemical kinetics carried out in an isoperibolic calorimeter operating quasi-isothermally. Both methods give very similar results for the reaction rate constant and enthalpy of reaction but fitting the reactor ...

Unified treatment of the pseudo-first order catalytic process for all stepped-potential methods
Journal of Electroanalytical Chemistry, 1998A general solution for any stepped-potential method in the case of the pseudo-first order catalytic process is presented. This solution is valid for a reversible redox reaction at a plane electrode whatever the magnitude of the forward and the backward rate constant of the parallel homogeneous chemical reaction.

Summary Relationships for spectrochemical evaluation of first-order and pseudo-first-order reactions following reversible electron transfer have been developed for chronoamperometry at optically transparent electrodes. Computer generated curves for the time dependent absorbance are presented for the general case where both electro-chemical and ...
