Experiment 24 - A Rate Law and Activation Energy Observe • To conduct an experiment in order to discover and calculate the expression known as the rate law for a particular reaction. • To conduct an experiment in order to determine the role each reactant plays within the reaction and the overall activation energy that is needed for a chemical reaction to occur all while utilizing an analytical tool. Procedure 1. Determination of Reaction Rates • Obtain boiled‚ deionized water‚ pipets or burets

The goal for our lab activity was to make a silver mirror by reducing silver ions with dextrose. The materials that we used were acetone‚ 5 mL of 1.5 M ammonium nitrate solution (NH4NO3)‚ 5 mL of 0.5 silver nitrate solution (AgNO3)‚ 10 mL of 5% dextrose solution (C6H12O6)‚ 10mL of 10% sodium hydroxide solution (NaOH)‚ a 50 mL beaker‚ a 250 mL Florence flask with a rubber stopper‚ a 10 mL graduated cylinder‚ a waste beaker‚ and distilled water. The first thing we did was rinsed the beaker‚ cylinder

Chemical Reactions & Equations CHEMICAL REACTION : In a reaction when the original state of the particle changes and it cannot be reversed by simple physical means‚ this type of reaction is known as chemical reaction. Example :- Fermentation of grapes‚ burning of wood etc. In this reaction we have seen that after burning of wood‚ coal is formed and we cannot make wood from coal. PHYSICAL REACTION : In a reaction when original state of the particle can be recovered by any means then this type of

Reaction on Reaction Paper The first thing that came to my mind when I have heard about Reaction paper is “What exactly is it?” and before I get an understanding of that‚ I resisted that change. But later‚ when I have studied about it and understood its purpose‚ I have started thinking “Why people avoid change at the first look without an analysis?” The general human tendency is to live in a comfortable zone in which he has lived for quite some time. He draws a circle‚ thinks that circle is his

L.O CYP 3.1 1.2 The difference between sequence of development and rate of development. Children will usually follow the same pattern of development‚ the ages of which they reach them could vary depending on them as an individual as each child is unique and will develop at their own rate. Goals of development are given on a wide average of when the children may be expected to reach this particular stage. In schools some children stand out from the rest of the class because they have reached

a‚ b) All children develop at their own rate and the term ’Sequence’ and ’Rate’ is used. The meaning for Sequence development is the order in which the child grows and the meaning for Rate is the speed that the child develops. The Development areas include Physical‚ social‚ communication and language‚ cognitive (intellectual)‚ emotional and behavioral and moral. Lots of the skills and the areas of development overlap one another so that the development is interconnected and linked which is called

The effect of time on enzyme reaction. Abstract: In this lab investigation we will observe how the amount of hydrogen peroxide is affected by catalase over time. The enzyme was added to 10 mL’s of hydrogen peroxide and observed over time to determine the relation between time and enzyme activity. The hypothesis stated that as time increased substrate would decrease. Therefore I predicted that at 60 seconds‚ there would be the least amount of H2O2. The enzyme activity mirrored my predictions

will affect it’s rate. The rate of diffusion will vary depending on the size of the particle. For example‚ a smaller particle will move faster than a large molecule at a given temperature . During reactions‚ when there is more energy‚ the reaction will take place at a faster rate. An increase in temperature will result in and increase in the amount of energy available‚ therefore the particle will move faster and the rate of diffusion will increase. Another factor affecting the rate of diffusing is

Is There A Relationship Between Body Temperature and Heart Rate? Statement of Research Question: This study sets out to determine whether there exists a difference in the average body temperature between males and females. Furthermore‚ the study aims to determine whether an increase in heart rate corresponds with an increase in body temperature. Data Collection: The data was obtained from the article “What’s Normal? -- Temperature‚ Gender‚ and Heart Rate” (Shoemaker‚ Allen 1996) as found in

PUTTING IT TOGETHER: Classifying Chemical Reactions Purpose: To observe and differentiate between the four different types of chemical reactions. Variables: The independent variables are the sodium chloride‚ sodium carbonate‚ magnesium‚copper‚ copper (11) sulfate‚ silver nitrate‚ oxygen‚ lead(11) nitrate‚ sodium carbonate‚ copper (11) sulfate pentahydrate. The dependent variables are the chemical reactions that are being looked for. For example decomposition‚ synthesis‚ single displacement or double
