What is the rate law for iodination of acetone?

The rate law for acetone iodination is rate= k[Acetone][H+]. The average value of k calculated from the three trials was found to be about 2.32e-5 M-1s-1.

What happens in iodination of acetone?

Iodination of Acetone An analogous reaction occurs between bromine and acetone. Since ketones are very weak bases, the equilibrium in the first reaction above is unfavorable for the formation of the ion. Under these circumstances [Ion] = K[Ac][H+], where K is the equilibrium constant for this reaction.

Why is iodination of acetone a zero order reaction?

The iodination of acetone is also catalyzed by hydrogen ions. The effects of varying the concentrations of acetone, iodine and hydrogen ions have been studied earlier and it has been found that the reaction is zero order with respect to iodine.

How is the iodination of acetone related to the rate law?

Kinetics Lab Explained: Iodination of Acetone. The rate of a reaction is proportional to the concentration of reactants. An equation called the rate law expresses the relationship of the reaction rate to the rate constant, k, and the concentrations of the reactants raised to some powers, x and y, found experimentally.

How is the rate of an iodination reaction determined?

The purpose of this experiment is to determine if the iodination reaction is a zero, first, or second order reaction. By systematically varying the concentrations of the reactants, the rate law is determined. The order of the reaction was also determined by creating an absorbance versus time plot with a linear fit for the rate law. …

How is the rate constant of an acid reaction determined?

To determine the rate constant at an assigned temperature Acid catalyzed iodination of acetone is a complex reaction. The rate law for overall reaction cannot be determined from the balanced equation for the reaction but from experiments.

How is the rate law for the reaction determined?

The rate law for overall reaction cannot be determined from the balanced equation for the reaction but from experiments. When an aqueous iodine solution is reacted with acetone in the prescence of an acid, the yellow color slowly fades as the iodine, I2, is consumed. The products of the reaction are iodoacetone and hydrogen iodide.
