Learning Objectives Chapter 14 Chemical Kinetics CHEM 1412 (Brown, LeMay, and Bursten 14ed) 14.1 Factors that Affect Reaction Rates 14.1a Explain the four factors that affect reaction rates in chemical reactions. (14.1) 14.2 Reaction Rates 14.2a Calculate the reaction rates from time and concentration data. (14.2) 14.3 Concentration and Rate Laws 14.3a 14.3b 14.3c Determine the reaction orders and the overall reaction order in a rate law. (14.3) Determine the units of the rate constant based on the overall reaction order. (14.3) Derive the rate law for a reaction given the experimental rate data. (Sample Exercise 14.6) (14.3) 14.3d Calculate the rate constant from the rate law and the experimental data. (Sample Exercise 14.6) (14.3) 14.4 The Change of Concentration with Time 14.4a 14.4c Determine time or concentration for both the first-order and second-order reactions using the integrated rate law and appropriate information. (14.4) Distinguish between a first-order and a second-order reaction from graphed data; identify what the slope represents. (14.4) Calculate the half life for first-order or second-order reactions.
