1) What is a reversible reaction? a) A reaction that only occurs in one direction. b) A reaction that occurs spontaneously. c) A reaction that can proceed in both forward and reverse directions. d) A reaction that produces equal amounts of reactants and products. 2) What chemical symbol represents a reversible reaction? a) Aq b) Rv c) Δ d) ⇌ 3) If a reaction is exothermic in the forward direction what will it be in the reverse direction? a) Exothermic b) Endothermic c) Spontaneous d) Irreversible 4) Two reactants require 30kJ to turn into products. What energy transfer is involved when the products turn into reactants? a) Exothermic b) Endothermic c) Spontaneous d) Irreversible 5) What is equilibrium? a) The state of a reaction where only reactants are present. b) The state of a reaction where only products are present. c) The state of a reaction where the forward and reverse reactions occur at equal rates. d) The state of a reaction where no reactants or products are present. 6) How is the amount of reactant changing at equilibrium? a) Increasing b) Decreasing c) Remaining constant d) Fluctuating randomly 7) How is the amount of product changing at equilibrium? a) Increasing b) Decreasing c) Remaining constant d) Fluctuating randomly 8) What is Le Chatelier's principle? a) The principle that states that reactions always go to completion. b) The principle that states that reactions at equilibrium can be shifted by changing the temperature. c) The principle that states that reactions at equilibrium can be shifted by changing the concentration, pressure, or temperature. d) The principle that states that reactions occur at equal rates in both forward and reverse directions. 9) A reaction is exothermic in the forward direction. What will occur if the temperature is increased? a) The reaction will become endothermic. b) The reaction will go to completion. c) The reaction will shift to favor the reverse direction. d) The reaction rate will increase. 10) A reaction is at equilibrium when some product is removed. What will occur? a) The reaction will shift to favor the forward direction. b) The reaction will shift to favor the reverse direction. c) The reaction will remain at equilibrium. d) The reaction will stop completely. 11) The reaction below is at equilibrium. What will occur when the pressure is increased? 2H₂(g) + O₂(g) ⇌ 2H₂O(g) a) The reaction will shift to favor the forward direction. b) The reaction will shift to favor the reverse direction. c) The reaction will remain at equilibrium. d) The reaction will shift to the side with fewer gas molecules.
