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

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

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

Module 1 Physics: The Basic Science What this module is about The study of science has two branches namely‚ the life sciences and the physical sciences. The life sciences include biology‚ zoology and botany. The physical sciences branch into areas such as geology‚ astronomy‚ chemistry and physics. However‚ physics is more than part of physical sciences because it does not only deal with matter and energy but it also deals with the other basic concepts like motion‚ forces‚ heat‚ sound‚ light

Free Fall Rachel Shea Physics 131 Lab‚ QL Hasbrouck 210 Sept. 21‚ 2014 Abstract This experiment measures the study of motion by observing the force of gravity acting solely upon an object‚ and also measures reaction time. If an object is in free fall‚ the only force acting upon it is gravity. The object used in this experiment was a golf ball that provided some acceleration when dropped. A sensor positioned underneath a table recorded the golf ball’s pattern of motion‚ when dropped. The main
