AP® Chemistry Kinetics Questions Free Response

tdwscience.com/apchem
This video covers a variety of kinetics problems that are similar to those that would be on a free response section of the AP Chemistry exam. The topics include: reaction rate, reaction kinetics, order of reaction, and order of reactants. We discuss how to read reaction graphs and determine whether a reaction is zero order, first order, or second order. We see how to write rate laws and determine rate constants from initial rates and experimental data. We also discuss reaction mechanisms, with slow and fast steps, and rate-determining and rate-limiting steps. Finally, we look at potential energy graphs for delta G, delta H, Gibbs free energy and Enthalpy. This can determine whether a reaction is exothermic or endothermic, exergonic or endogenic. Finally, activation energy peaks for the individual steps of a reaction correlate to the speed or rate of different steps of the reaction.
