EQUILIBRIUM UNIT. Thomas Wenzel, Bates College. The problem sets on chemical equilibrium can be used in at least two different manners. The primary intent is to use these as a set of in-class, collaborative learning exercises. Groups of 3-4 students work together in discussing and working through the problems.

16 ( Chemical Equilibrium. ANSWERS to THE I.C.E. BOX The ICE box is an organizational tool to keep track of chemicals before, during, and after a chemical reaction. Consider the reaction: 2N2O(g) + O2(g) 4NO(g) If we started with 1.0 M N2O and 1.0 M O2 only, the reaction might go until we have 2.0 M NO. Follow the steps.

Practice Problem Answers. The following reaction is at equilibrium: 4NH3 (g) + 3O2 (g) ↔ 6H2O (g) + 2N2 (g) How will the equilibrium shift if: The volume is increased. Since the volume is being increased, the pressure is dropping. In response, the equilibrium will shift right to attempt to make more moles of gas and increase the pressure
