16.4 Short Answer Questions 1) Explain dynamic equilibrium. Use the generic reaction A(g) ? B(g) to explain. 2) Why is an equilibrium constant unitless? 3) Can the Kp and Kc for a reaction ever have the same value? Why or why not? 4) Why aren’t solids or liquids included in an equilibrium expression? 5) How is the reaction quotient different from an equilibrium constant for a given reaction? 6) Define Le Chatelier’s Principle. 7) How will equilibrium be affected, with the same number of moles of gas on both sides, if the pressure is increased?
