A book review project takes shape with the help of ChemTwitter community.

The AP Chemistry Exam is getting closer. What will you provide your students to review for the big day?
A common topic in chemistry discussion groups and forums is about the use of the terms “spontaneous reaction” versus “thermodynamic favorability”. This is a new activity for chemistry students who struggle with the correlation between changes in enthalpy, temperature, entropy, and the Gibbs free energy of a system; which relies on an analogy that most students will be familiar with.
Let me share some tips I learned reading the Advanced Placement Chemistry Exam in Salt Lake City, Utah.
Answers to common questions about the AP Chemistry Exam format, content, and grading.
I taught my students how to use the method of initial rates. I taught my students rate laws. However, they strugged to differentiate when to use what method. Upon further probing, they struggled to articulate why one might use one method over the other. They could parrot back some ideas ("The rate law tells you about the particles involved in the rate determining step of the reaction."), but I wasn't convinced of mastery and connections.
