Joseph Marcus Experiment 15: The Oxidation of Alcohol 07/03/2009 Purpose and Objective: The purpose of this lab is to examine the rate of reaction of the oxidation of ethanol to produce ethanol by potassium dichromate. The reaction is a second order reaction, but because of the high concentration of one of the reactants (which remains relatively constant in the reaction), the reaction displays characteristics of both first and second order rates. The rules for assigning oxidation states are also an essential part of this lab and are used throughout this experiment. Another important aspect of this experiment is the absorption and its direct relationship to the concentration. Because of this direct relationship, the time-dependent absorption can be placed into the integrated rate law in place of the concentrations. The spectrophotometer is used in this experiment to measure the absorption as a function of time, and a plot of ln[(A 0 -A )/(A t - A )] vs. time and 1/(A t -A ) vs. time are produced to examine the first order and second order rate constants respectively.
