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

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

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

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

THE COLOR WHEEL G.TAMIZH Color has played an important role in communication‚ psychology‚ and even physical health giving color power. Whether it is in interior design‚ graphic design‚ or fine art‚ it can affect the mood in different ways. Let’s take a look at the color wheel which is important and sometimes can be intimidating for designers and artists. The color wheel is made up of twelve basic hues: three primaries‚ three secondary‚ and six tertiary. The color wheel is a circular display of

Hair coloring or lightening is the practice of changing the color of hair. During lightening‚ hair goes through various stages until it reaches the ideal orange/gold color. Lightening time varies‚ depending on natural hair color. The darker the hair‚ the longer the lightening time needed. Medium brown hair on average takes somewhere around 40 minutes to lighten. Dark brown hair takes somewhere around fifty minutes to lighten. Darkest brown hair takes around sixty minutes to lighten. And black hair
