Activation energy, concentration-time calculations.
Determining the rate law using the initial rate method.Relation of boiling points and melting points to intermolecular forces.These are the topics you should be familiar with before taking the exam: Basic Chemistry Energetics (thermochemistry of thermodynamics).There are ten main content categories on the exam: The ACS General Chemistry Exam contains 70 multiple-choice questions and has a time limit of 110 minutes. How to Study for the ACS General Chemistry Exam.Once you’ve had a chance to look at the course, we’d love to hear what you think via this short and sweet feedback form. Students can also evaluate their progress using quizzes, unit tests, and the course challenge. Mastery-based practice that allows students to repeat exercises, seeing new questions each time, until they feel like they’ve mastered the concepts.Many of the videos are worked examples of open-ended questions, helping students better prepare for free-response questions on the exam. More than 100 new videos covering everything from photoelectron spectroscopy to intermolecular forces.Every question includes hints or rationales to help students improve their understanding. Over 640 AP -style questions tightly aligned to topics on the exam.In its current form, AP Chemistry beta covers topics from the first seven units of AP Chemistry. Eventually, the beta course will replace the older AP Chemistry course that is already on Khan Academy. What do we mean by “beta” in this context? In short, this course is work in progress: not only will we be adding more content over time, but we’ll also be making changes to already-released content based on feedback from users like you. Khan Academy is excited to announce the launch of a brand-new science course: AP® Chemistry beta!
