Chemical Thermodynamics Quiz

This online quiz is intended to give you extra practice in Gibbs free energy (ΔG) and entropy (ΔS) calculations for a variety of chemical and physical processes. This quiz aligns with AP® Chemistry Learning Objectives 9.1 Introduction to Entropy, 9.2 Absolute Entropy and Entropy Change, 9.3 Gibbs Free Energy and Thermodynamic Favorability, and 9.5 Free Energy and Equilibrium; and NGSS standards HS-PS1-4, and HS-PS3-1.
