AP Chemistry — Chemical Reactions

Unit 4 of 9

Chemical Reactions is the fourth of 9 units in the College Board's current AP ChemistryCourse & Exam Description. It builds on Intermolecular Forces and Properties and sets up Kinetics.

Our Chemical Reactions set has 12 practice questions, each with a written explanation, a one-line key takeaway, and a rationale for every wrong choice — so you learn why the right answer is right and why each distractor is tempting. You can work them as a timed set or read the worked solutions straight through.
