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

EXECUTIVE SUMMARY One of the most important tasks that a petroleum engineer has to undertake is determining how much hydrocarbons are contained in a potential reservoir. Key physical characteristics that they will be concerned with include porosity‚ permeability‚ net-to-gross ratio and bulk rock volume. This information can then be used to calculate original oil in place (OOIP) and original gas in place (OGIP). Hence‚ for a given exploration prospect‚ explorers and commercial analysts can

Despite following rigorous experimental procedures‚ there are limitations that exist‚ but were not addressed due to insufficient time and limited resources to carry out the experiment. Firstly‚ varying the length of boiling might not be the best method to determine the amount of calcium ions. If time permits‚ I could perhaps investigate other variables such as pH‚ surface area and concentration and their effect on calcium leaching. Moreover‚ I could also use other types of fish soup stocks and compare

The paintings of Jean-Auguste-Dominique Ingres and Frank Duveneck show the juxtaposition between the high society‚ in the portrait of Mademoiselle Jeanne Gonin‚ and the gritty working class population‚ in the painting The Cobbler’s Apprentice. These oil-on-canvas portraits reflect their differences through stylistic qualities and subject matter‚ through the use of brush stoke and light they convey different messages to the viewer. Ingres’ painting of a somber looking wealthy woman is an oil-on-canvas

FE 315 INSTRUMENTAL ANALYSIS High Performance Liquid Chromatography (HPLC) Instructor: Dr. Hüseyin BOZKURT High Performance Liquid Chromatography (HPLC) is one mode of chromatography‚ the most widely used analytical technique. Chromatographic processes can be defined as separation techniques involving mass-transfer between stationary and mobile phases. Present day liquid chromatography that generally utilizes very small packing particles and a relatively high pressure is referred to as high

In physics‚ the charge of a volume is commonly described by a quantity called the charge density or the charge distribution. When the electric field that arises from the charge distribution exhibits a volumetric symmetry‚ a handy relationship known as Gauss’s Law may be used to calculate the charge distribution of the volume. The charge volume of a ball or rod mill is expressed as the percentage of the volume within the liners filled with balls or rods. When the mill is stationary‚ the charge
