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...
