  1. Resources and Activities • Textbook - chapter 15 & ppt file • Online practice quiz • Chemical Equilibrium handouts and problem sets • Lab activity • POGIL • Chem Guy video lecture series on Chemical Equilibrium (several) http://www.cosmolearning.com/courses/ap-chemistry-with-chemguy/video-lectures/ or start with http://www.youtube.com/watch?v=FHPxpkcA6Z4 • Chemtour videos from Norton N2O4(g) 2NO2(g) Chemical Equilibrium • Chemical equilibrium occurs when a reaction and its reverse reaction proceed at the same rate. • Once equilibrium is achieved, the amount of each reactant and product remains constant. http://www.chem.iastate.edu/group/Greenbowe/sections/projectfolder/animations/no2n2o4equilV8.html

  2. Activities and Problem set for chapter 15 (due date_______) Lab activities: • Le Châtelier principle(wet lab) POGILS (1) : Chemical Equilibrium Online practice quiz ch 15 due by_____ Chapter 15 worksheets, notes and practice problems sets In class preview and then Independent work - students to view animations & interactive activities (5 in total from Norton) and write summary notes on each.
