These practice problems for AP® Chemistry will help you study for the test, and get a five!
http://www.tdwscience.com/apchem These multiple choice problems are written to be as close as possible to the real AP® Exam. They cover all of the usual topics: stoichiometry, gas laws, kinetics, equilibrium, acids and bases, thermodynamics, thermochemistry, electrochemistry, le chatter's principle, Gibbs free energy, entropy, and enthalpy. For each problem, we talk about the tips and tricks to solve it. We also work through strategies to outsmart the test, and see how to tackle concepts more quickly and efficiently. I hope this helps you ace the test and get a five!
