2015 Q4CALCULATING THE EQUILIBRIUM CONCENTRATION OF ALL SPECIESNameSection1. Below are 1.0 L containers for the initial and equilibrium condition for the reaction,A2(g) ! D2(g) ! 2AD(g)Calculate the magnitude of the equilibrium constant for the reaction.Container BeforeReaction StartedContainer After ReactionAchieves EquilibriumShow work:2. Set up the ICE table for the following general chemical equation. (Assume the reaction proceeds fromleft to right to establish equilibrium.)A2(g) ! D2(g) ! 2AD(g)Gelder/McGaw3

OTHER POSSIBILITIES:1. Describe the contents of the container below. Be sure to discuss the contents interms of elements or compounds; pure substances or mixtures(homogeneous/heterogeneous); and the phase. Clearly label the contents so yourdiscussion can be accurately interpreted.b.The sample in part a) is cooled to the point that the contents of the container are in theliquid phase only. Use the empty container below to draw what you believe thecontents of the container will appear. Clearly describe the nature of your drawing so asto address the composition of the contents. Again be sure you clearly label thecontents.Gelder/McGaw6
2. Given the containers belowABCQuestioni) Indicate the letter of one containerrepresenting a heterogeneous mixture ofelements. Indicate the phase(s) present.Answer:ii) Indicate the letters of TWO containersdepicting a phase change. Indicate the phaseof each substance initially and finally. Be sureyou label each substance with its phasechange.iii) Indicate the letters of TWO containersdepicting a chemical change. Write a balancedchemical equation that describes the reaction.Include the correct phase for each substancein your balanced equation.Gelder/McGaw7DE
MULTIPLE CHOICE1.The diagram above represents H2(g) and N2(g) in a closed container. Which of thefollowing diagrams would represent the results if the reaction shown below were toproceed as far as possible?N2(g) 3 H2(g) à 2 NH3(g)Gelder/McGaw8
2.(A)(B)(C)(D)The diagram above represents a mixture of NO2(g) and N2O4(g) in a 1.0 L container at agiven temperature. The two gases are in equilibrium according to the equation2 NO2(g)N2O4(g)Which of the following must be true about the value of the equilibrium constant for thereaction at this temperature?K 00 K 1K 1K 13. The following diagram represents a gas sample.Which of the following could represent the same gas at a lower temperature?Gelder/McGaw9
4. Which of the images below best represents an ionic compound like NaCl dissolved in water?A.B.C.D.Gelder/McGaw10
