Title: Kinetics: The Rate of a Chemical Reaction Objectives: 1. To study the kinetics of chemical reaction‚ 2 I- + S2 O82- I2 + 2 SO42- . 2. To study the effects of reactant concentration (persulphate‚ S2O82-‚ and iodide‚ I-) and temperature on the rate of chemical reactions. ( i) Study the effect of 0.20M (S2O82-) on the rate of chemical reaction. ( ii) Study the effect of 0.10M (S2O82-) on the rate of chemical reaction. ( iii) Study the effect

This assignment discusses chemical kinetics by determining the rate and average value for rate constant based on experimental values given. The orders of the reactants can only be determined experimentally‚ so we must look at how the concentration of the reactants affect the instantaneous initial rate while holding the concentration of the other reactant constant. In this reaction‚ the overall reaction order for the rate law is third because the order for A is second and the order for B is first

A KINETIC STUDY OF AN IODINE CLOCK REACTION PURPOSE To investigate the kinetics of the reaction that occurs between iodide and persulfate ion. You will: (1) determine the rate law‚ (2) determine the numerical value of the rate constant at room temperature‚ (3) explore the effect of temperature on the reaction and determine the activation energy (Ea)‚ and (4) investigate catalytic activity of selected metal ions on the reaction. INTRODUCTION Reaction times vary from picoseconds (10-12 seconds)
