Exothermic reaction

The reaction between Propanone and iodine under acidic condition Aims To find the order of reaction with respect to propanone, iodine and sulfuric acid, thus proposing a rate equation. Find rate constant at various temperature and with the use of the Arrhenius equation, find the activation enthalpy of the reaction. General Method {For step by step guide of the experiment see preparation page} By using known concentration of aqueous iodine solution (0.000 moldm-3, 0.005 mol dm-3, 0.015…

Abstract: The Grignard reaction was successfully accomplished. An amount of 1.20 ml of 2-methyl-2-pentanol was collected, and 9.60% yield was calculated based on the theoretical yield. Despite the low amount of 2-methyl-2-pentanol, its identity was confirmed by comparing the experimental refractive index and infrared spectrum to the literature refractive index and infrared spectrum of 2-methyl-2-pentanol. Statement and purpose The purpose of this experiment is to synthesize a specific alcohol…

A Molecular Explanation of How the Fog Is Produced When Dry Ice Is Placed in Water The primary purpose of the article is to correct a common misconception about the origin of the fog, in the Dry Ice in Water Fog (DIWF), and to give further insight into happenings on a molecular level in the (DIWF) with the aid of experimental evidence. The writer is keen on proving that the fog produced in the (DIWF) demonstration is actually from the bulk water onto which the dry ice is placed and not the…

Initially, sand and hydrogen peroxide were added in a test tube to create a mixture. Based on the observation conducted, no reaction was visible (i.e. no gas occurred). In result, the solution did not react because it does not contain the desired enzyme in order to break down H2O2. An enzyme is needed to decompose H2O2 into water and oxygen. With this knowledge, students were able to determine that the results for the rest of the tests did make sense. For example, the solution contained…

Step 1 - Synthesis A mixture of compressed CO2 and ammonia under 240 bar (g) pressure is reacted to form ammonium carbamate. This is an exothermic reaction, and heat is absorbed by a boiler to produce steam. The first reactor achieves 78% conversion of the carbon dioxide to urea and the liquid is then furthurly purified. Then, the second reactor receives the gas from the first reactor and recycles the solution. Conversion of carbon dioxide to urea is approximately 60% at a pressure of 50 bar…

combustion reaction tends to be less complete. The bigger the molecule of alkenes, the more likely to get a yellow, sooty flame. B. Action of sulphuric acid (to be performed under fume hood) 1. When concentrated sulphuric acid was added into cyclohexane, is there any sign of reaction? Ans: No. 2. Do the substances mix or are there two separate layers in the test tube when concentrated sulphuric acid was added into cyclohexene. Explain the reason behind the reaction. Ans:…

1.1 Problem Summary Ravi raj Chemicals Company manufactures the sulphamic acid. During the process scrubber through SO3 gas liberate the atmosphere. So these SO3 undesirable gases are reducing. The SO3 gas is hazards and it is pollute the atmosphere. In this project we can solve the possible solution then apply to the plant scale. 1.2 Objective Of Projects In these manufacturing process of sulphamic acid first raw material put at the batch…

free energy (∆G) of a reaction is defined as the measure of the thermodynamic force that drives a reaction to occur. When ∆G is positive, it indicates that a reaction will not occur spontaneously while when ∆G is negative, the reaction is spontaneous. The Gibbs free energy equation is given by : ∆G = ∆H –T∆S ∆H refers to the enthalpy and is a measure of the actual energy that is released when the reaction occurs. A negative value of ∆H means the reaction is exothermic while a…

of certain chemical elements within numerous everyday products (either inside the polymeric material or as an external layer) that help combat the ignition through chemical reactions at particular phases in the combustion cycle. Fire retardants are classified as reactive (which is combined into polymers through chemical reactions) or additive (combined into the compounds through physical mixing). Fire retardants composite of the following…

Calcium hydroxide (Ca(OH)2), universally referred to as lime water or slaked lime is formed by reacting hydrated lime (calcium oxide, CaO) with water (H2O)[1] CaO (s) + H2O (l) ⇌ Ca(OH)2 (aq) (ΔHr = −63.7 kJ/mol of CaO) Calcium hydroxide is an economically favorable alkaline reagent to neutralize acid as it yields 2 moles of (OH)2 for every 1 mole of Ca(OH)2 (which is slightly soluble in water) when compared to sodium hydroxide [1] and it may separate from the solution ‘constant agitation must…
