Explain. • Determine the rate law for the reaction between bleach and two dyes • Determine the rate constant for the same reaction. Introduction In this lab, you will be determining how quickly household bleach reacts with a couple of different dyes. In order to be able to understand this, we have to first visit the world of kinetics. Kinetics. 5 Nov 2008 Laboratory Report Materials Chemistry Laboratory Introduction This reaction is kinetically of second order, not as be expected, third order. In order to find the rate, we need to take the concentration of the reactant and raise it to the reaction order, which will be found during the experiment. To understand a reaction and determine this rate order, we need to be able to understand the rate law which is Rate = k[A]x.
Part A: Determining the complete rate law The order of reaction with respect to the iodate ion, m, must be determined for the following rate. It is assumed. A major part of this lab was finding the reaction order X and Y, as well as the rate constant for this specific reaction. To find reaction order X and Y, a formula was used using the average rates from experiment one and three, as well as the molarity concentration of potassium permanganate. Catalog No. AP7644 Publication No. 7644 Kinetics of Crystal Violet Fading AP* Chemistry Big Idea 4, Investigation 11 An Advanced Inquiry Lab Introduction Crystal violet is a common, beautiful purple dye.

To calculate a rate constant from experimental data. Introduction Chemical kinetics deals with the speed, or rate, of a reaction and the mechanism by which the reaction occurs. We can think of the rate as the number of events per unit time. The rate at which you drive (your speed) is the number of miles you drive in an hour (mi/hr).
As well another way that the procedure can be improved upon is to perform the lab like a titration lab using a burette, flask and the indicator. Also because the assumption was made that the reaction order of the bisulfate was zero because it was constant throughout may have affected the results. The reaction orders can be obtained by the method of initial rates or by linearizing the concentration vs. time plot with the integrated rate law of the appropriate order (zeroeth, first, or second order). The reaction will be forced into pseudo-order conditions by using a huge excess of hypochlorite and a limiting amount.
