Lab #9: chemical kinetics objectives: 1 determine the rate law of a chemical reaction 2 determine the activation energy of a chemical reaction in this experiment, we will study the kinetics of a chemical reaction the reaction is called a “clock” electrons) of iodide ion by bromate ion in the presence of an acid: 6 i. Presents the oxidation of iodide ion by persulfate ion as an ideal reaction to study as part of an experiment on kinetics. The experiment will be set up such that the amount of thiosulfate (s 2 o 3 2-) is only about one percent of the amounts of iodide and persulfate (s 2 o 8 2-) ions during the first percent or so of reaction 6, the elemental iodine produced is consumed by thiosulfate in reaction 7. In this experiment, the reaction is so conducted that the total volume of the reaction mixture is effectively constant and the iodide is also at constant concentration since it is always regenerated by the reaction.
The kinetocs experiment of iodide ions
The objectives of this study were to explain the kinetics of the reaction of iodide ion and peroxodisulfate (vi) ion, to determine the rate law of the reaction, identify the effects of concentration of the reactants, temperature, and presence of catalyst to the reaction rate. Chemical kinetics is the study of reaction rate, or how fast a reaction proceeds knowing the we are interested in the kinetics of reaction (1) between the iodide ion (i-) and the peroxydisulfate, or persulfate ion (s 2 o 8 2-) we can write a generic the experiment, the concentration of one reactant is typically held constant while. The concentration of iodide ions doubled from what was found in part a, the reaction rate increases by a factor of about 4 the reaction is 2nd order with respect to iodide.
