This package includes six worksheets that cover all of the major standards in the equilibrium unit for AP Chemistry. Each worksheet contains a detailed answer key that includes graphs and long explanations when they are appropriate. Here is a short description of each worksheet:
Problem Set 1 explores the how the forward and reverse rates of reactions are related to equilibrium. It also includes a few problems that require students to draw pressure vs. time graphs, which is something that shows up on the AP test but is often not included in textbooks.
Problem Set 2 includes quantitative problems in which students must calculate equilibrium constants and compare Q vs. K. Students must then decide in which direction the equilibrium will shift.
Problem Set 3 includes more quantitative problems involving the equilibrium constant. Students will need to use ICE tables and the assumption when dealing with very small equilibrium constants. Students will also examine how the total pressure of a system is changed when the equilibrium shifts.
Problem Set 4 examines solubility. Students will use Ksp to calculate the molar solubility of compounds and to determine whether precipitation will occur when solutions are mixed together. The concept of saturation is tested, and students must determine what will happen to the concentration of ions when saturated solutions are evaporated or diluted.
Problem Set 5 examines Le Chatelier’s Principle in a qualitative manner. Students will determine how changes in temperature, volume, pressure, and concentration will affect various equilibriums. Students will also examine whether these changes increase, decrease, or do not impact the equilibrium constant.
Problem Set 6 involves a quantitative examination of Le Chatelier’s Principle. Students will use Le Chatelier’s Principle along with stoichiometry to make quantitative predictions about the end result of shifts in equilibrium.
This product goes well with the equilibrium review guide that is also listed in this store, which includes a textbook like explanation of the major concepts in equilibrium.
