The acid-catalyzed iodination of acetone
CH3COCH3(aq) + I2(aq) → CH3COCH2I(aq) + HI(aq)
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.
Determine the rate law for this reaction.

Interpretation:
The rate law should be determined for the given chemical reaction.
Concept Introduction:
Rate law: It is generally the rate equation that consists of the reaction rate with the concentration or the pressures of the reactants and constant parameters.
Rate constant: The rate constant for a chemical reaction is the proportionality term in the chemical reaction rate law which gives the relationship between the rate and the concentration of the reactant present in the chemical reaction.
Answer to Problem 90IL
The rate law for the given reaction is as follows,
Explanation of Solution
The rate law is obtained by first determining the order of each reactant present in the given reaction. The order of each reactant is obtained by using the given set of concentration and the rate data as follows,
The order for
The order for
Similarly, the order for
The order for
Similarly the order for
The order for
Therefore, the rate law for the given reaction is as follows,
The rate law for the given reaction was determined.
