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

This assignment discusses chemical kinetics by determining the rate and average value for rate constant based on experimental values given. The orders of the reactants can only be determined experimentally‚ so we must look at how the concentration of the reactants affect the instantaneous initial rate while holding the concentration of the other reactant constant. In this reaction‚ the overall reaction order for the rate law is third because the order for A is second and the order for B is first

types of forces involved. Two of the main forces experienced are called potential energy and kinetic energy. Potential energy is the energy an object has depending on the position of it. For example the higher an object is the higher the potential energy is and the lower an object is the less potential energy it will have. Kinetic energy is also a main type of force that is involved with rollercoasters. Kinetic energy is the energy an object will have as it is in motion. There are many different types

Most street barriers are made of hard rubber or plastic materials that easily give in or dent when hit. Why is this so? A. To reduce the vehicle’s kinetic energy when it collides with the barriers B. To store potential energy in the bumpers of vehicles C. To reduce the impact force when hit by a vehicle D. To reduce the impact time when the barriers hit the vehicle 9. What is the momentum of a 20

1.0 ) THEORY (I) Static Stability of Floating Body Referring to Figure 1‚ the weight W of the floating body passes through its center of gravity G. The upthrust or buoyancy force FB acting on the floating body passes through the center of buoyancy B‚ which corresponds to the centroid of the displaced fluid. When the floating body is subjected to a small angular displacement or perturbation θ about its equilibrium upright configuration‚ the center of buoyancy shifts from B to B’‚ while the center

Pablo Cuate Biochemistry Lab Report Objective: The purpose of this lab is to analyze enzyme activity at pH neutral for acid phosphatase as the colorless p-nitrophenylphosphate (PNPP) substrate concentration changes. We will empirically determine the concentration of production formation‚ Vmax and Km from absorbance of yellow PNP in the reaction. Results Figure 1 This figure indicates a positive linear trend for the concentration of PNP and absorbance. Table 1: Absorbance Value for Acid Phosphatase

Abstract To determine the rate law with respect to bleach and blue dye‚ a series of graphic and algebraic manipulations were done on the data obtained in the kinetic trace experiment in order to determine the different components that made up the rate law. Using absorbance spectroscopy to monitor concentration over time‚ rate order of the dye was found to be 1st order through the integrated rate law and through the proportionality method; the order of the bleach was also determined to be 1st order

Huckleberry Finn is a static character. Throughout the realistic‚ historical fiction novel‚ The Adventures of Huckleberry Finn by Mark Twain‚ the main character Huck travels with a fugitive slave‚ Jim. Constantly‚ Huck’s internal conflict between helping a fugitive slave‚ and turning him in‚ divides him. Huck ultimately ends up helping Jim‚ but treating him as subhuman‚ and taking advantage of his companionship. Huckleberry Finn wavers in his moral ideas‚ but undergoes no development. He starts to
