About

This quiz focuses on chemical kinetics, specifically rate laws and reaction orders, which are fundamental concepts in Advanced Placement Chemistry. The questions assess students' ability to determine rate laws from experimental data, calculate rate constants with proper units, identify reaction orders for individual reactants and overall reactions, and understand the relationship between stoichiometric coefficients and rate law exponents. Students must master the skill of analyzing concentration-time data to determine how changes in reactant concentrations affect reaction rates, distinguish between reaction order and stoichiometric coefficients, and apply mathematical reasoning to calculate rate constants with appropriate units based on the overall reaction order. The complexity and depth of these problems, including multi-step data analysis and unit calculations, clearly indicate this material is designed for grade 11-12 students enrolled in advanced chemistry coursework. Created by Bonnie Wehausen, a Chemistry teacher in the US who teaches grades 11 and 12. This quiz serves as an excellent formative assessment tool for AP Chemistry students working through kinetics units, particularly effective for checking understanding after initial instruction on rate law determination. Teachers can use this quiz as a warm-up activity to activate prior knowledge before diving deeper into kinetics problems, as homework to reinforce classroom learning, or as a review session before unit tests or AP examinations. The progressive difficulty of questions makes it ideal for scaffolded practice, allowing students to build confidence with basic rate law concepts before tackling more complex data analysis problems. This assessment aligns with AP Chemistry Learning Objectives related to Big Idea 4 (Chemical Reactions) and supports students in developing the quantitative reasoning skills essential for success on the AP Chemistry examination, particularly in areas covering reaction rates, rate laws, and experimental determination of kinetic parameters.

The rate law for the reaction 2NO(g) + O2(g) → 2NO2(g) is first order in O2 and third order overall. What is the rate law for the reaction?

Rate = k [NO]2[O2]2
Rate = k [NO]1[O2]2
Rate = k [NO]2[O2]1
