Study Guide Overview
This study guide covers entropy and spontaneity, focusing on absolute entropy (S°) and change in entropy (ΔS°). It explains how to calculate ΔS° using standard entropy values and predict its sign based on phase changes, number of moles, and molecular complexity. The guide also includes practice problems and emphasizes the concept of state functions. Key exam topics and tips for predicting and calculating entropy changes are provided.
