Title: Kinetics: The Rate of a Chemical Reaction Objectives: 1. To study the kinetics of chemical reaction‚ 2 I- + S2 O82- I2 + 2 SO42- . 2. To study the effects of reactant concentration (persulphate‚ S2O82-‚ and iodide‚ I-) and temperature on the rate of chemical reactions. ( i) Study the effect of 0.20M (S2O82-) on the rate of chemical reaction. ( ii) Study the effect of 0.10M (S2O82-) on the rate of chemical reaction. ( iii) Study the effect

?Chemical Medications or Natural Healing Many times when people get sick they go to the doctor to be diagnosed‚ then they make their way to the pharmacy to pick up the prescriptions the doctors say you need to cure the problem. What if the prescription is wrong? But is there a better solution? Natural healing is much better than any chemical medication the doctor prescribes to you because they are natural and more effective. Many prescriptions are easy to overdose on‚ and usually end in death

natural‚ and great for us‚ right? As it turns out‚ this is not necessarily the case. In the past few years‚ I used agave syrup or nectar in several recipes before I heard some negative things about it. I have looked at where agave comes from‚ the chemical composition‚ how it is metabolized‚ calorie content and what it may be used for. Only now do I have a full grasp of the process it goes through to be used as a sweetener and how that may affect us. Agave syrup comes from the agave plant‚ which

Introduction Victoria Chemicals is one of the leading producers of Polypropelene‚ a polymer that is used in many products ranging from carpet fibers‚ automobile automobile components‚ packaging film and more. When Victoria Chemicals started up in 1967 they built two plants‚ one in Merseyside‚ England and one in Rotterdam‚ Holland. Both plants were identical to each other and produced an equal amount of goods. Morris Greystock‚ the controller of the Merseyside plant had notice a decline in

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

What Factors Affect Chemical Equilibrium? Introduction: In investigation 14‚ “What Factors Affect Chemical Equilibrium?”‚ the purpose was to find out which reagents caused a change in the chemical equilibrium. A deep red color was formed when Iron Nitrate [Fe(NO3)3 (aq)] was mixed with water and Ammonium Thiocyanate [NH4NCS (aq)]. The product of these two reactants was Iron Thiocyanate(FeNCS). After different trials of mixing the given reagents
