Practice Problem: ICE Box Calculations

Professor Dave explains how to calculate equilibrium concentrations using an ICE box method. The video covers setting up the equilibrium expression, using stoichiometry to determine changes in concentration, and solving a quadratic equation to find the equilibrium concentrations of PCl5, PCl3, and Cl2. The tutorial emphasizes understanding the process and provides additional resources for further learning.
