concentration of a species can affect reaction rate in the determination of rate law and rate constant. 2. To determine how temperature affects reaction rate. Introduction Chemical kinetics deals with the speed‚ or rate‚ of a reaction and the mechanism by which the reaction occurs. We can think of the rate as the number of events per unit time. The rate at which you drive (your speed) is the number of miles you drive in an hour (mi/hr). For a chemical reaction the rate is the number of moles that react

the rate of photosynthesis using leaf discs. Aim : To measure the effect of light intensity on the rate of photosynthesis in leaf discs. Introduction : The simple concept of photosynthesis is that it can occurs in the presence of light‚ which takes place in the chloroplasts of green plant cells. Photosynthesis can also be defined as the production of simple sugars from carbon dioxide and water causing the release of glucose and oxygen. The chemical equation for photosynthesis can

Introduction Photosynthesis takes place in the chloroplast and is the use of sunlight energy for cell processes. It happens through a number of chemical reactions and the transfer of electrons. It is used as the source of energy (ATP) for plants. The reaction equation for photosynthesis is H2O + CO2 + (Light) (CH2O)N + CO2 In the Hill reaction‚ Robert Hill showed how chloroplasts in water can still function if there is light and an electron acceptor to release oxygen. He proved that the oxygen

INTRODUCTION The measurement of fluid flow is very important in our daily life from measurements of blood-flow rates in human artery to the measurement of liquid oxygen in a rocket. In this experiment‚ students are to adapt to various ways to measure the flow of essentially incompressible fluids by using the flow measuring apparatus. Students will also be able to understand the application of Bernoulli’s equation in this experiment. The flow is measured by using a venture meter‚ an orifice meter

This lab report will be detailing the steps taken and the results discovered when using spectrophotometry to determine the percentage of copper in a copper-clad penny and the thicknes of the copper layer on the copper-clad penny. After 1982‚ copper coating has been used in the creation of the penny because the cost of pure copper has increase to the point that the amount needed t omake a penny cost far more than the actual value of the penny. This lab allowed us to see just how much copper coating

CHM1032L pre/post lab instructions Preparation is a key to success in this lab. For this reason‚ you are required to thoroughly read through the experiment information presented in the lab manual‚ and complete a pre-lab for each experiment you do. The prelab must be completed prior to the day of the experiment. Each Friday I will ask to see your completed prelab before I allow you to enter the lab. If you have not finished the pre-lab‚ I will not allow you to enter the lab and you will receive

Discussion Heart Rate Our hypothesis stated 1.) The heart rate increases substantially when a person performs a physical activity and 2.) Females have heart rates greater than males’. In this experiment we measured the resting heart rates and exercise heart rates of both the male and females that are in the class. We calculated the results that were taken by each member of each group in the class (6 males and 16 females total). The average resting heart rate for women was 71.8 beats per minute

Lab 4: Photosynthesis and Chromatography of Spinach Leaves Discussion: The chromatography of the spinach leaves was taken to establish what pigments were present in the chloroplasts of the leaves. The solvent carried and separated the different pigments up the cellulose paper. The solvent moved up the paper because of capillary action because of adhesion of the solvent molecules and the paper. The pigments dissolved in the solvent also were carried up the paper and were separated because

Lab Report The Effect of Resting on Clothespin Squeezing. Hypothesis: If you rest then the clothespin squeezing rate will increase. Materials:- Clothespin Clock Sneakers Procedure: Separate class into two groups (exercisers and resters). Exercisers will do jumping jacks for a minute. Exercisers and registers will squeeze clothespin for a minute Repeat steps two and three. Total of three trails. Precaution: Shoes must be tied. Space between exercisers. Healthy exercisers

Photosynthesis Lab Kozlowski Kendal Schweiss Hour 6 Introduction: Photosynthesis is carbohydrate production using light and chlorophyll. It is a process when green plants and other organisms turn carbon dioxide and water into carbohydrates and oxygen‚ using light energy trapped by chlorophyll. The rate of photosynthesis can be measured by either the disappearance of substrate or the accumulation of product. 2H2O + CO2 + light -> carbohydrate (CH2O) + O2 + H2O There is a spongy mesophyll
