AP Chemistry · Unit 5: Kinetics

5.1 Reaction Rates

In short

You must understand that the kinetics of a chemical reaction is defined by the rate at which reactants are converted to products over time. You are expected to relate the rates of change of specific reactant and product concentrations directly to the stoichiometry of the balanced chemical equation.

What else do you need to know about Reaction Rates?

The focus in this topic is on foundational definitions and qualitative relationships, setting the stage for mathematical rate laws in subsequent topics.

How is Reaction Rates tested on the exam?

This topic is primarily assessed through Science Practice 6.E (Argumentation), which requires you to provide reasoning to justify a claim using connections between particulate and macroscopic scales or levels. On the AP Exam, you may be asked to explain why a specific experimental parameter (such as temperature or surface area) changes the reaction rate, linking macroscopic observations to particulate-level interactions. Questions may appear in both the multiple-choice (50% of exam weight) and free-response (50% of exam weight) sections.
