Estimation of the Activation Energy for the Iodination of Acetone Through the Effect of Temperature on the Rate Constant Joel Costa‚ Alex Fuentes‚ Michael Chea‚ Rex Nwerem Dr. Morgan Ferguson July 9‚ 2013 ABSTRACT | It is often important to determine the rate at which a chemical reaction takes place‚ i.e.‚ how fast it yields the desired products. Temperature is one of the factors that influence the rate of reactions and it does so by providing energy to reactant particles so that a larger

In this project a 95 000 MT/A of acetone will be produced annually which is equivalent to 206 kg/hr. The process that been used is the dehydrogenation of isopropyl alcohol (IPA). There is 6 main equipments used in order to produce acetone‚ and the equipment are mixture drum‚ there is no reaction take place in Mixing drum ( V-401 )‚ the main reactor ( R-401) the reactor been used is a tubular flow reactor‚ in this reactor the conversion of IPA will produce 85% acetone and 5% is water ‚next major equipment

Balances‚ Numerical Methods Design Project Production of Acetone Process Description Figure I is a preliminary process flow diagram (PFD) for the acetone production process. The raw material is isopropanol. The isopropanol (lPA) feed is a near azeotropic mixture with water at BB wt yo IPA at 25"C and I atm. The feed is heated‚ vaporized‚ and superheated in a heat exchanger (E-401)‚ and it is then sent to the reactor (R-401) in which acetone is formed. The reaction that occlrrs is shown below.

Planning Aim In this experiment I will be testing the effect of temperature on the plasma membrane of a beetroot. I will do this by measuring the percentage light transmission using a spectrophotometer. Once I have obtained my results‚ I will justify them using scientific knowledge explaining what I have observed whilst carrying out the experiment. Factors to be controlled "« The pH concentration "« Regular use of distilled water "« Ensuring that the surface area of each piece of beetroot is

Introduction The production of acetone and butanol by means of solvent-producing strains of Clostridium spp. was one of the first large-scale industrial fermentation processes to be developed‚and during the first part of this century it ranked second in importance only to ethanol fermentation. The reason for the almost total demise of this fermentation in the early 1960s was the inability of the fermentation process to compete economically with the chemical synthesis of solvents. However‚ interest

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.

Effects of Temperature on Beetroot Cell Membranes Background Information: A cell membranes is a thin structure that surrounds the whole cell. It contains the cytoplasm of a cell. The cell membrane is made up of hydrophilic region and a hydrophobic region. The hydrophilic region likes water‚ it is on the outside of the cell‚ the hydrophobic region is the inside of the cell where its protected from H2O. The cell membrane’s outer surface lets larger molecules into the cell. The inner surface deals
