Unformatted text preview: be to determine the order for the hydrolysis reaction with respect to the [Co(en)2Cl2]+ ion. For one of the two parts, you will be given data that was collected previously for the decrease in [Co(en)2Cl2]+ ion over time, from which you can deduce the order of the reaction. Specifically, by finding the best function of chloro complex concentration that gives the best linear correlation, we can determine the order of the reaction. 67 For the other part, you will use a complementary method for determining the order of reaction. You can examine half-lives using the following rationale for Part I. At a particular acid concentration, you may assume that the hydrolysis rate can be expressed by the relation: Rate = k[Co(en)2Cl2+]n where n = 0, 1, or 2, and here the square brackets indicate molar concentrations. To find the order of this reaction we will measure the dependence of the initial concentration, C0, of the [Co(en)2Cl2]+ ion on the time required for the reaction to proceed half-way to completion. It can be shown that for zero, first, and second order re...
