Reaction

The rate at which a reaction occurs, referred to as reaction rate, is a type of reaction property that directly measures the extent of a reaction. Changes in concentration affect reaction rates in chemical formulas, and if the reaction is not specifically known, the rate cannot be determined. The rates are given in negative or positive measurements depending on whether the concentration is a reactant or product. Knowing this, the first step in finding the reaction rate would be to determine the…

Iodine clock reactions also known as Landolt Clock Reactions are one of many types of reactions in Chemistry. Clock reactions are an appealing way to show different type of chemicals having a reaction towards each other. This type of chemical reaction shows the demonstration of chemical kinetics. Iodine clock reactions were discovered by Swiss chemist Hans Heinrich Landolt in 1886. The procedure of conducting an iodine clock reaction consist of two colourless chemicals being mixed together.…

explore how different factors affect the reaction rate of enzymes reacting with their corresponding substrates in order to learn more about how enzymes function in different environments. The independent variables investigated in this experiment were the concentration of different substrates, the temperature of the environment, and the effect of a catalyst on the reaction rate. The dependent variable for all of the investigations was the time it took for the reaction to occur. To investigate…

resulting from reactions with chemicals in its environment. The oxygen oxidizes with the metal, and the sodium help speed up the corrosion process. The presence of oxygen and electrolytes (Sodium – Na) in sample number 2 make it more…

I predict that the higher the temperature of the solution the faster the reaction will take place because the particles will collide more when the temperature rises. The aim of this experiment was to test if the temperature affects the rate of reaction between hypo and dilute hydrochloric acid? How does temperature affect the rate of reaction between hypo and dilute hydrochloric acid? The kinetic particle theory explains the properties of different states of matter. The particles in solids,…

and had a reaction rate of 0 seconds-1. The 0.1 v/v % hydrogen peroxide concentration recorded a reaction rate of 0.17 seconds-1. The 0.2 v/v % hydrogen peroxide concentration, recorded a lower reaction rate than the 0.1 v/v% at 0.14 seconds-1. The 1 v/v % hydrogen peroxide concentration recorded higher at 0.49 seconds-1. The 3 v/v % hydrogen peroxide concentration recorded the highest reaction rate at 1.57 seconds-1. The 5 v/v % hydrogen peroxide concentration recorded a lower reaction rate…

In week one Polymerase chain reaction (PCR) was used to amplify RTKs that were derived from thoroughly smashing five fruit flies and was combined with 1 ml Buffer A (630 ul ddH2O, 100ul 1M Tris/Hcl pH7.6, 200 µl 0.5M EDTA, 20 µl 5M NaCl, and 50 µl 10% SDS), then incubated for 15 minutes at 65˚C so that as much DNA could be secluded as possible. 200 ul of KAc/LiCl working solution, 1 part 5M KAc (potassium acetate) and 2.5 parts 6M LiCL (lithium chloride), mixed and chilled for a full 10 minutes.…

physical appearance. In part I, reaction one produced a blinding, bright white light when the metal burned and the metal turned into a white powdery substance. For reaction two, there was no reaction at first and it took a long time for it to react, but then bubbles started to form around the magnesium ribbon and the substance turned into a pink-yellowish color around the magnesium strip when it was placed in the 150 milliliters beaker. The physical observations of reaction three was the…

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…

The rate at which a reaction takes place can be affected by the temperature, the concentration, the particle size, and by using a catalyst but two that really affect the reaction are temperature and concentration of the solute and solvent. The rate of a reaction is determined by the temperature and the concentration which in this case determine how fast or slow the reaction will occur. In both cases something is being increased, for example, placing solutions A and B in the warmed water…
