1. Experimental Methods The aims of this experiment to determine the rate of the reaction by using tubular flow reactor data‚ to demonstrate the temperature dependence of the reaction and also the rate constant and to observe the effect of different flow rates to the conversion. It is a homogenous reaction with only liquid phase is present. Also the reaction is endothermic. The saponification reaction is as follows; NaOH + EtOAc NaOAc + EtOH The reactants were taken as 1:1 ratios. 0.1 M NaOH

Abstract To determine the rate law with respect to bleach and blue dye‚ a series of graphic and algebraic manipulations were done on the data obtained in the kinetic trace experiment in order to determine the different components that made up the rate law. Using absorbance spectroscopy to monitor concentration over time‚ rate order of the dye was found to be 1st order through the integrated rate law and through the proportionality method; the order of the bleach was also determined to be 1st order

A KINETIC STUDY OF AN IODINE CLOCK REACTION PURPOSE To investigate the kinetics of the reaction that occurs between iodide and persulfate ion. You will: (1) determine the rate law‚ (2) determine the numerical value of the rate constant at room temperature‚ (3) explore the effect of temperature on the reaction and determine the activation energy (Ea)‚ and (4) investigate catalytic activity of selected metal ions on the reaction. INTRODUCTION Reaction times vary from picoseconds (10-12 seconds)

Kinetics” experiment was done to investigate the changes in the rate of reaction under the effect of concentration‚ temperature‚ and presence of a catalyst. It was determined that as the concentration of reactants and the temperature increases‚ the rate of the reaction increases as well. Also‚ the reaction was run by the presence of catalyst‚ and the rate of the reaction increased drastically in the presence of it. The order of the reaction with respect to each reactant was calculated to be: x = 1 [I-]

catalysts‚ on the rate of a reaction. The rate law of a reaction was determined using the initial rates of method. Data gathered from six different runs of a reaction between thiosulfate and hydronium ion was used to plot a linear equation based on the Arrhenius equation. From the equation‚ the activation energy‚ Ea‚ of the reaction was obtained with an experimental value of 58.03 kJ/mol. The experiment showed that higher temperature leads to an increase in the rate of reaction‚ that a decrease in
