4. The reaction: 2 C102(aq) + 2 OH (aq) → CIO;'(aq) + Cl0,'(aq) + H2O(1) was studied with the following initial concentrations of reactants at 50°C: Experiment [C1O,1 (M) [OH] (M) Initial Rate: (M/s). 1 0.060 0.030 0.0248 2 0.020 0.030 0.00276 3 0.020 0.090 0.00828 a) Determine the rate law for the reaction. b) Calculate the rate constant, k, for this reaction using the data from each run and then calculate the average value for the rate constant, k. c) Using the average value for the rate constant, calculate the initial rate of the reaction when the initial concentrations of the reactants are [C1O2] = 0.10M and [OH]= 0.050M.

3. Fill in the missing reagents in the following flowchart. Ph Ph CHO Ph Br. Br Ph Ph- Ph Ph Ph Ph Ph Ph Ph Ph -Ph

Organic Functional Groups Identifying positions labeled with Greek letters in acids and derivatives If possible, replace an H atom on the a carbon of the molecule in the drawing area with a methyl group substituent, and replace an H atom on the ß carbon with a hydroxyl group substituent. If one of the substituents can't be added for any reason, just don't add it. If neither substituent can be added, check the box under the drawing area. HO Oneither substituent can be added. OH 0/5 X

I need help with 3b and 3c with an explanation.
