Introduction The purpose of this experiment was to determine the rate law graphically from the rate of disappearance and the x y values also the specific rate constant (k). Activation energy was also determined‚ and the effect of catalyst was evaluated in the reaction between peroxodisulphate ion S2O82-‚ and iodide ion‚ I-. S2O82-(aq) + 3 I-(aq) --> 2 SO42-(aq) + I3(aq) The general expression for the rate law‚ given this overall reaction‚ is: rate of disappearance of S2O82- = k[S2O82-]m[I-]n Chemical

selecting variables In this lab‚ we will be studying the difference of heart rate between boys and girls. There are many things that can increase heart rate‚ such as exercise‚ drinking coffee‚ taking certain pills‚ drinking an energy drink‚ feeling a strong emotion‚ etc. I have chosen to use exercise as a means of increasing the heart rate of my subjects‚ more precisely‚ 20 sit-ups. There are many reasons why your heart rate increases when you exercise‚ the most important one being that your muscles

Aim of the experiment: In this experiment I will investigate the relationship between the concentration of the hydrochloric acid and the rate of a reaction. To find this out I will react different concentration of hydrochloric acid and magnesium‚ from there I will monitor the gas (hydrogen) produced and analyse the results. Prediction: I predict the higher the molarity of the hydrochloric acid the faster the rate of reaction therefore the quicker the gas will be produced in the specific time

Fixing an Epidemic: American Dropout Rates In the United States there are tons of problems affecting our youth‚ one very prevalent issue affecting the American youth for a long time has been the very high rates of school dropouts. According to DoSomething.org‚ a non-profit helping raise awareness on various issues affecting young people‚ there is one student who decides to give up on school every 29 seconds. This calculates to approximately 1‚000‚000 American dropouts a year‚ 7‚000 a day (DoSomething)

Crime Reporting & Rates Response Paper UOPX CJS_200 01/18/2013 1) What is the purpose of major crime-reporting programs? What makes a successful crime-reporting program in the United States? There are a few factors for the purpose of having a crime-reporting program‚ other than just collecting crime statistics. One of the many reasons why crime-reporting is so important is because they can determine if any new programs‚ or new laws‚ or new techniques that were implemented are working

planning‚ improved medicine‚ low death rate‚ lack of global epidemics‚ and poor education…etc. These are the main reasons behind overpopulation. Overpopulation has bad impact on many aspects in our life such as: environment‚ society‚ and economy. The solution for such an issue like growth of population is not this much easy it should contain combine efforts from many parts. The reason for that is because the causes of overpopulation are very massive‚ so the solutions should be equally varied. One of the

Some Causes of Fertility Rates Movements Claire Norville Rocio Gomez Robert L. Brown ABSTRACT Fertility patterns are different between countries and over time. Many different factors can affect the fertility rate. This paper will discuss the different factors that have an effect on the fertility rate. Some are economic while some are social. The economic factors will be based in the theories of Richard Easterlin‚ Diane Macunovich‚ Butz & Ward‚ and John Ermisch. The social factors that
