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

Descriptive essay Eng- 111 17‚ September 2010 Upon opening my eyes as I wake up I stretch while taking a glance at the cursing clock that seems to hate me. I call my clock that because every day it seems as if it wants to wake me up at a later time each day. Than as my thoughts start to gather I realize that it’s the weekend‚ which means I can finally relax. I told myself that once the weekend comes I need to go get my nails done and finally relax and release all the stress and tension. In my

1. History The invention of epoxy resin has undergone a long period of time. As early as 1891‚ the German Lindmann hydroquinone and epichlorohydrin with the reaction of condensation into the resin and make use of anhydride curing. But its value has not been revealed. Epoxy plastic has its roots far back in history‚ to be specific‚ in 1936‚ when Dr. Pierre Castan in Switzerland succeeded in synthesizing an epoxy resin that he hardened with pthalic acid anhydride. Dr. Castan’s work was licensed

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.

Pigments were first extracted from tomato paste by a 50/50 mixture of acetone/hexanes; these miscible molecules act together as one organic solvent. Pigments choose the organic layer over the tomato paste with water‚ which allowed for their extraction. K2CO3 is an ionic base that was added to deprotonate the citric acid. The ionic product of the reaction in figure 3 now prefers the aqueous layer‚ which serves to wash the pigments of the acidic impurity. Saturated NaCl pulls any water into the

experiment is to see if we can recycle polystyrene using acetone. If this is possible‚ this can be used to help improve our environment since polystyrene itself is not biodegradable. Hypothesis: I hypothesis that polystyrene‚ mainly known as styrofoam‚ can be recycled using acetone. This cost efficient and easy method will not only motivate both individuals and industries to recycle but also improve the state of our environment.

The mixture was then filtered by using Whatman No. 4 filter paper in to a glass beaker. 300ml of other solvent‚ Chloroform‚ was then added in the residue for 2-3 days. Similarly the mixture was filtered by using whatman No. 4 filter paper. After chloroform‚ Acetone and Methanol were added in residue for sequential extraction. Solvents; Hexane‚ Chloroform
