Rates of Reaction: Iodination of Acetone Introduction: The rate at which a chemical reaction occurs depends on several factors: the nature of the reaction‚ the concentrations of the reactants‚ the temperature‚ and the presence of possible catalysts. In this experiment you will study the kinetics of the reaction between iodine and acetone in acid solution: For this reaction‚ you will determine the order of the reaction with respect to acetone and HCl and find a value for the rate constant‚ k.

is first-order. This can be seen as follows: [S] [2 x 10-5] Is Km < 0.01 ? [5 x 10 -3] = .004 Yes‚ first order a) Since this is a first order reaction we can use the following equation to determine the rate constant‚ k. 0.693 0.693 0.693 k = t1/2 k = 6 min k = 6 min k = 0.115 min-1 b) k = Vmax / Km Vmax = k x Km

carried out by using a large excess of NaOH (more than 10-fold) with respect to the substratecrystal violet such that the reaction (CV+ + OH-↔ CVOH) obey the pseudo-first order reaction rate equation -d[CV+]/dt = kw[CV+][OH-]=k[CV+] Where k=kw[OH-] is the pseudo-first order rate constant and kw is the second order rate constant. Assuming the absorbance at the λmax of the reaction mixture to be due to the CV+ only‚ we obtain ln(A0/A)=kt Where A0 is the initial absorbance and A is the absorbance at time

Some people are too dependent using calculator in solving simple equation. This attitude will lead people not using critical thinking in solving an equation instead they use calculator for faster result and convenient way. In addition on that‚ internet are vastly used nowadays‚ some students used internet for their projects and searching some articles. Instead
