| | Kinetics Author: Katie Wood Instructor: Donald Kavanagh Chem 106b‚ Section 001 Lab Performed 8th‚ 2012 Lab Report Submitted February 22nd‚ 2012 Abstract The purpose of the lab was to determine the order of reaction for the dye Red #40. By measuring the reaction rate between bleach and the dye‚ the order of the reaction was determined to be first order. Introduction The study of kinetics is important for studying the amount of time it takes for a particular reaction to reach

1 Measuring and calculating equilibrium constants Clearly‚ if the concentrations or pressures of all the components of a reaction are known‚ then the value of K can be found by simple substitution. Observing individual concentrations or partial pressures directly may be not always be practical‚ however. If one of the components is colored‚ the extent to which it absorbs light of an appropriate wavelength may serve as an index of its concentration. Pressure measurements are ordinarily able to measure

Lab Report Iodination of Acetone Temperature as a Variable Objective The objective of this lab is to determine the energy of activation of the iodination of acetone. This will be done by performing the reaction at differing temperatures. The same reaction orders we obtained for the previous lab will be incorporated into this experiment. The equation Ea = -8.31 x slope of ln k vs. 1/T(K) will be used to determine the energy of activation required for this this reaction. Hypothesis

9/23/12 Lab Report #1 Meter Reading Summary The objective of this experiment was to learn how to read different meters like the D.C. volt meter and the D.C. amperes meter. In all meters each big line is a major division and each little line in between is a minor division‚ and if there is a line smaller than the minor division lines then that would be a sub minor division. Each meter has a low‚ medium‚ and high range. For example on the D.C. volt meter the ranges go from top to bottom 150‚ 15‚

Lab Report Diffusion is - One of two kinds of passive transport‚ - Diffusion can transport ions from higher concentration to lower concentration region without any other forces. - A net movement of molecules in and out of cell membrane - Diffusion can be affected by the steepness of the concentration gradient. Lab question: Is the rate of diffusion influenced by the presence of second molecule? Prediction: the rate of diffusion is influenced by the presence of second molecule

Maryely Ramirez Professor Theresa Sterner Bio Lab 105 04 November 2013 The Effects Environmental Temperature and pH have on the Activity of Porcine Pancreatic Amylase Introduction There are many types of enzymes and each has a specific job. Enzymes are particular types of proteins that help to speed up some reactions‚ such as reactants going to products. One of them is the amylase enzyme. Amylases are found in saliva‚ and pancreatic secretions of the small intestine. The function of amylase is

The effective doses of serratiopeptidase were fixed to be 10 mg/kg‚ b.w. and 50 mg/kg‚ b.w. orally. The solubility of serratiopeptidase was found to be in water and was insoluble in ether and alcohol. Fenofibrate was considered to be as reference standard [13]. LD50 of fenofibrate (standard) was found to be >1242 mg/kg‚ p.o. the effective dose of fenofibrate was considered to be 65mg/kg‚ b.w‚ orally. The solubility of serratiopeptidase

during the lab session Procedure Part A This lab was performed by the group members as they closed both low and high flow rotameters (Fig-2) and filled the tank with water. Then‚ the large rotameter was opened when the water in the tank had reached the internal baffle‚ so the flow from the tank was reduced by doing so. One member was in charge of adjusting the level of the water so it was always maintained over the baffle’s level during the lab (Fig-1). The first part of the lab was done

Lab Report Marisa McKinney P. 2 Purpose: To investigate the periodic variation of density in Group 4A elements. Background: When the elements are arranged in order of increasing atomic number‚ they exhibit periodic recurrence of properties. Elements in the same group in the periodic table tend to have similar physical and chemical properties. These similarities are due‚ in large part‚ to similarities among the electron configurations of the elements in a group. You can find periodic
