3. Explain how you can determine the pseudo rate constant k' for Run 1 from a graph you prepared in Q1 above. Plot the appropriate graphs for Runs 2 and 3 and write all three k' values to the table at the top of page N-14. Be sure to indicate units for k' and to express your k' values using an appropriate number of significant digits. (1.0) 4. Calculate the initial concentrations of OH (aq) 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) 0.000012 0.00001 0.000008 0.000006 [CV]/M 0.000004 0.000002 0 0 20 40 60 80 100 120 140 Time / sec 1200000 1000000 800000 600000 1/[CV] 400000 200000 0 0 20 40 60 80 100 120 140 Time / sec 0 0 20 40 60 80 100 120 140 -2 -4 -6 -8 In[CV] -10 -12 -14 Time / sec M-25 nm Observation Sheet: Effect of Concentration on Rate of Reaction Approximate Molarity of stock crystal violet (CV+) solution: 3.00*105 mol/L Wavelength of maximum absorbance (Imax): 588.5 Molar Absorptivity of CV+ at Imax (from advance study assignment): 8.32 x 104 L/(mol.cm) Molarity of NaOH used in Run 1: 3.00.810 mol/L Molarity of NaOH used in Run 2: 2.00x10 mol/L Molarity of NaOH used in Run 3: T.
