CHEM 1112 Kinetics of the Persulfate – iodide Clock Reaction The purpose of this experiment is to determine the rate law and the activation energy for the reaction between persulfate ion‚ S2O82-‚ and iodide ion‚ I-: S2O82-(aq) + 2 I-(aq) 2 SO42-(aq) + I2(aq) The rate law can be written as Reaction rate = (1) Where m and n are the orders with respect to S2O82- and I-‚ respectively‚ and k is the rate constant. Determining the rate law involves determining the values

Statistics means different things to different people. According to the Merriam-Webster Dictionary‚ Statistics is the practice or science of dealing with the collection‚ analysis‚ interpretation‚ and presentation of numerical data. Basic statistic data are collected by statisticians or mathematicians. There are different types and levels of statistics. The different levels call for different statistical techniques. There are four types; the lowest of the four ways to characterize data is Nominal

Introduction This project aims to discover which houses are more expensive in jesmond and walker. Source of determination is carried out by a random survey and primary research. Hypothesis. It is an ascertained fact that houses in jemsond are more expensive than those in walker due to the fact that jesmond has a greater distance from the industrial area than that of walker. Background In the past few year‚ prices of houses in the United Kingdom has increased rapidly due to inflation. The government

You ever read a boring book and wonder who the static character is? Well not many people do with the book To Kill a Mockingbird because it’s not boring. Jem and Scout‚ the brother and sister of the book have both evolved from the beginning of the end of the book. However‚ the question is who’s the most changed character? There may be some reason to Scout being the character who has changed the most but there are plenty of reasons Jem is the most changed character.Therefore‚ being the older brother

What is a static budget? A static budget is a budget that does not change as volume changes. If a company’s annual master budget is a static budget‚ the budget for sales commissions expense will be one amount such as $200‚000 for the year. In other words‚ in a static budget the budgeted amount for sales commissions expense will remain at $200‚000 even if the actual sales during the year are $3 million‚ $4 million or $5 million. In contrast to a company’s static master budget‚ the company’s sales

A World Without Friction (603 Words)Although friction may seem like a minor issue‚ its absence would chance life as we know it. There would be many negative effects of this like not being able to gain traction on any surface and your ipods earplugs always falling out. Also‚ there would be many positive effects‚ such as eliminating the need for coolant in engines and lubricant in machines. Moreover‚ the absence of friction would be both bad and good. Without friction‚ many obvious things which we

Kinetic and Thermodynamic Reaction Condition Brandon Bullock 2/10/15 Objective The purpose of this experiment is to test kinetic theory by running several reactions and determine which product are formed under kinetic conditions and which products are formed under thermodynamic conditions. Kinetically controlled products have low transition states. This makes it easy for the product to be formed at low temperatures

(9 points) In Part 1‚ did the force of friction on the shoe depend on the weight of the shoe? If the two are related‚ why are they? What is the slope of the line on the graph of force of friction vs. weight‚ and what does that number represent? Explain using your data. Answer: The frictional force did depend on the weight of the shoe. The more mass a shoe had‚ the
