The kinetics of the reaction

was studied in basic aqueous media by Chia and Connick [J. Phys. Chem. 63:1518 (1959)]. The initial rate of I- dis- appearance is given below for mixtures of various initial compositions, at 25°C (None of the solutions initially con tained OI- or Cl-):

Initial composition of I-(M)	Initial composition of OCl-(M)	Initial composition of OH- (M)	Initial rate (mol I- L-1s-1)
2 X 10- 3	1.5 X 10-3	1.00	1.8 X 10-4
4 X 10- 3	1.5 X 10-3	1.00	3.6 X 10-4
2 X 10- 3	3 X 10-3	2.00	1.8 X 10-4
4 X 10- 3	3 X 10-3	1.00	7.2 X 10-4

a. The rate law can be expressed in the form
Find the values of a, b, and c.
b. Calculate the value of k, including its units.
c. Show whether this rate law is consistent with the mechanism
