AP FRQ ARCHIVE. Here you’ll find links to the released FRQs from previous AP Chemistry exams. Here’s the MCQ Archive page. Other FR exams have been released by the College Board, but they are considered ‘secure’ (yes I know that’s naive and hilarious) so they are not linked. All links are to external content that I do not control, and ...
Here are all the actual AP Chemistry free response questions from the 2014 through 2018 exams. Also includes scoring guidelines and sample responses.
Explore timing and format for the AP Chemistry Exam. Review sample questions, scoring guidelines, and sample student responses.
The AP Chemistry Exam will test your understanding of the scientific concepts covered in the course units, as well as your ability to design and describe chemical experiments. A scientific or graphing calculator is recommended on both sections of the exam.
A student obtains a solution that contains an unknown concentration of Fe2+(aq). To determine the concentration of Fe2+(aq) in the solution, the student titrates a sample of the solution with MnO4 (aq) , which converts Fe2+(aq) to Fe3+(aq), as represented by the following equation.
Here you’ll find links to worked answers to FRQs from previous AP Chemistry exams. Every released FRQ from 1990 to 2023 has a worked answer. 2020 was a COVID interrupted year, and no formal exam questions were released into the public domain by the College Board, although AP teachers do have access to questions from 2020.
The seven free-response questions cover all nine units in the chemistry course and will require application of all six science practices. You should pace yourself to allow for approximately 23 minutes each for the long questions and about 9 minutes each for the short questions.
Questions 4–7 are short free-response questions that require about 9 minutes each to answer and are worth 4 points each. Write your response in the space provided following each question.
