Calculate the initial concentrations of OH-(ag) for each kinetics run: these initial concentrations represent the concentrations of OH at the moment of mixing, before any reaction with CV+ has taken place. Place these values into the table on page N-14 (1.0) N-14 k' k Run # [CV](M) [OH-]i(M) Units: Units: 1 2 3 5. Using the ratio method described on pages M-5 and M-6, determine the partial order of the reaction with respect to the hydroxide ion. To do this, perform the calculation three times: compare Run 1 to Run 2, compare Run 1 to Run 3, and compare Run 2 to Run 3. Determine the average of your three results, and round it to the nearest integer. (1.0) 6. Calculate the value of k for each run and add these values to the table at the top of this page and indicate the units for k. Show your calculations for Run 1. Determine the average overall rate constant k. (1.0)
