The kinetics of the Harcourt-Essen Reaction (Hydrogen peroxide variation) Aims: To find the order of the reaction with respect to the Hydrogen Peroxide (H2O2)‚ Potassium Iodide (KI) and the Sulphuric Acid (H2SO4) by the use of an Iodine clock reaction. Calculate the rate constant‚ mechanism and equation Find the effects of temperature on the rate of reaction The effects of a catalyst on the rate of reaction Find the activation enthalpy (Ea) of the reaction‚ with and without a catalyst Background:

A hypo-kinetic disease is a disease that is associated with a lack of physical activity or lack of exercising. Obesity is an example of a hypo-kinetic disease‚ which makes sense because it is a condition of an accumulation of excessive body fat as a result of not creating a caloric deficit as well as not being physically active. Obesity affects the body by changing the normal body composition. It affects cardio-respiratory endurance‚ flexibility‚ muscle endurance and how much power and strength one

In this essay‚ it will be discussed how the Kinetic Molecular Theory explains many gas law specifically Boyle’s gas law‚ Charles’ gas law‚ and Avogadro’s gas law. To understand what will be talked about is to first know what the Kinetic Molecular Theory is. In our textbook is says it is “A simple model for gases that predicts the behavior of most gases under many conditions.” First off‚ we will take a look at Boyle’s Law. As stated in our lab manual “at constant temperature the pressure which a given

Introduction Chemical Kinetics‚ described as the study of rate of chemical processes‚ varies on many factors to determine the time needed for a reaction to complete. The rate of reaction of a chemical reaction is important‚ as reactions are of little use if the time period needed for the reaction to occur is too lengthy. Many factors influence the rate of a chemical reaction‚ such as temperature‚ concentration and surface area. The order of the reaction is based on the concentration of the reactants

Abstract The “Chemical Kinetics” experiment was done to investigate the changes in the rate of reaction under the effect of concentration‚ temperature‚ and presence of a catalyst. It was determined that as the concentration of reactants and the temperature increases‚ the rate of the reaction increases as well. Also‚ the reaction was run by the presence of catalyst‚ and the rate of the reaction increased drastically in the presence of it. The order of the reaction with respect to each reactant

Isokinetic dynamometry testing on male university sport and exercise science students looking at Hamstring/Quadriceps ratio‚ peak torque‚ peak torque to body mass ratio and power. Abstract Isokinteic dynamometry testing is important in monitoring injury and performance. There are few studies that have looked at male university sport and exercise science students bilateral difference of the hamstrings and quadriceps at 60˚s and 180˚s.The purpose of the study was to look at injury and performance

Kinetic Expressions (Kinetics) has been taking place at Berea College for 20 years. This year the team celebrated its 20th by revisiting a choreography that was performed at the first Kinetics and were very purposeful of who they allowed to choreograph in this production. This will be a critique of some of the dances performed; it will go into detail about each dance‚ analyze the movements and reveal the message. The opening act to Kinetics this year was the choreography that was performed at

Kinetic energy is increasing between letters A-B‚ C-D and E-F. Based off the observations‚ in phase A-B Tert-Butyl Alcohol stays a solid‚ in phase C-D Tert-Butyl Alcohol stays a liquid‚ and in phase E-F the chemical stays a gas. This is observed at the particle level because temperature is a measure of Ek; the temperature is increasing which increases kinetic energy. Since Ek is the energy of motion‚ the particles would increase their velocity and the number and force of collisions. However‚ the
