CHEMISTRY FREE-RESPONSE QUESTIONS 6. Answer the following questions, which pertain to binary compounds. (a) In the box provided below, draw a complete Lewis electron-dot diagram for the IF3 molecule. (b) On the basis of the Lewis electron-dot diagram that you drew in part (a), predict the molecular geometry of the IF3 molecule. (c) In the SO2 molecule, both of the bonds between sulfur and oxygen have the same length. Explain this observation, supporting your explanation by drawing in the box below a Lewis electron-dot diagram (or diagrams) for the SO2 molecule. (d) On the basis of your Lewis electron-dot diagram(s) in part (c), identify the hybridization of the sulfur atom in the SO2 molecule. The reaction between SO2(g) and O2(g) to form SO3(g) is represented below. o 2 SO (g) 2 SO2(g) + O2(g) m 3 The reaction is exothermic. The reaction is slow at 25qC; however, a catalyst will cause the reaction to proceed faster. (e) Using the axes provided on the next page, draw the complete potential-energy diagram for both the catalyzed and uncatalyzed reactions. Clearly label the curve that represents the catalyzed reaction. GO ON TO THE NEXT PAGE. CHEMISTRY FREE-RESPONSE QUESTIONS (f) Predict how the ratio of the equilibrium pressures, pSO2 pSO3 , would change when the temperature of the uncatalyzed reaction mixture is increased. Justify your prediction. (g) How would the presence of a catalyst affect the change in the ratio described in part (f)? Explain. STOP END OF EXAM
