Question:

The acid-catalyzed iodination of acetone

is a common laboratory experiment used in general chemistry courses to teach the method of initial rates. The reaction is followed spectrophotometrically by the disappearance of the color of iodine in the solution. The following data (J. P. Birk and D. L. Walters, Journal of Chemical Education, Vol. 69, p. 585, 1992) were collected at 23°C for this reaction. Experiment 1 2 3 4 LO 5 Initial Concentrations [CH3COCH3] 1.33 1.33 0.667 0.333 0.333 (mol/L) Initial Rate
