This is a flipped classroom module that covers the concepts of time-integrated rate laws. This activity is designed to be done at the end of the typical second quarter/second semester general chemistry kinetics unit. Students will be expected to have learned the following concepts prior to completing this activity:
a) how instantaneous rates of reactions are determined by measuring changes in concentration of reactants and/or products at the beginning of the reaction;
b) understanding basic rate laws and how rate laws are determined for a chemical reaction using instantaneous rates;
c) understanding why the rates of reactions slow down as the time of reaction increases.

Students are expected to achieve the following learning goals:
a) conceptually understand how time-integrated rates laws can be used to describe the kinetics of a chemical reaction;
b) use time-integrated rate laws to determine the rate constant for a first or second order reaction;
c) use time-integrated rate laws to determine the half-life of a decomposition reaction;
d) use Excel to plot time-integrated rate laws and generate best-fit linear trend lines.
Students need a laptop or tablet device capable of operating a spreadsheet/graphing program.
