Kinetics Lab – Methanolysis of Diethyl Succinate

Abstract: The purpose of this experiment is to determine the rate constant and activation energy in the first step of the methanolysis of diethyl succinate.  The rate constant is determined by analyzing the amount of diethyl succinate present in the reaction mixture at different times in a Gas Chromatogram.  The k1 at 50 degrees Celsius was .0298 while the k1 at 60 degrees Celsius was .0332. Introduction: Gas Chromatography can be used to analyze the kinetics of a reaction that […]

FIRST ORDER CHEMICAL KINETICS: INVERSION OF SUCROSE ABSTRACT

By: Carla Mateo The main purpose of the experiment is to measure the rate of inversion of sucrose and its dependence on temperature.  When discussing inversion, the origin of the usage of the term, in this context, comes from the way that the measurement is carried out.  The sugar syrup concentration is measured using a polarimeter.  The light, which is plane polarized, passes through a solution, a sample of pure sucrose, it undergoes a rotation.  It is optically rotated to […]
