Question

Calculate the orders of the reaction with respect to I–, BrO3 , and H+ –
using the aforementioned systematic approach. In order to simplify this task, the proper experiments are provided. The orders should be rounded to the nearest integer.

For example, for the [I] for reaction mixture #1, 2 mL of 0.010 M KI was used. So we obtain: M = (0.010 M· 2 mL)/10 mL = 0.0020 M Use this procedure to complete the reactant concentrations for the other four mixtures. Calculating the Orders of the Reaction Calculate the orders of the reaction with respect to I, BrO,, and H* using the aforementioned systematic approach. In order to simplify this task, the proper experiments are provided. The orders should be rounded to the nearest integer. Include your calculations on the following pages.

PART A. Rate Dependence on Concentration Fill in the table below. (Note: The reactant concentrations in the mixtures are not the same as the stock solutions. These reagents were diluted by the other solutions. See the example calculation below.) Temp.

We can use the equation: M V stock stock M V mixture mixture are the concentration and initial volume of the stock solution and M are the concentration and final volume of the reaction mixture). Rearranging this equa- tion to solve for the reactant concentration (M ), and substituting 10 mL for Vu Wwe obtain: (where M and V stock stock mixture and V тіxture mixture' mixture M mixture (М.
