Quiz today… Problems: Hour Exam I, Fall 2006, #6 Carbon monoxide poisoning can take place because Hemoglobin (Hgb) binds to carbon monoxide more tightly than oxygen. The reaction can be described as follows: HgbO2 (aq) + CO (aq) HgbCO (aq) + O2 (aq) Keq = 60 What is ΔGo for this reaction at room temperature? Stuck? Start by looking at Sample Exercises 16.9 and the proceeding discussion (pgs 766-767 of Zumdahl). Hour Exam I, Spring 2007, #11 You are trying to learn more about the process of calcination, which involves converting CaCO3 (limestone) into quicklime (CaO). Quicklime played an important role in the construction of Roman aqueducts and other buildings; it was commonly mixed with water and used as mortar in order to hold the large stones together. Being a chemist, you are interested learning a bit more about the chemistry of this process, but the text that you are using is only giving you bits and pieces of data, including: CaCO3 s CaO s + CO2 g The equilibrium temperature for this process is 834 oC, and ΔSorxn for this process is 152 J/K (you can assume ΔSo and ΔΗο are temperature independent for this problem). What is ΔGorxn for this process at room temperature? Hour Exam I, Spring 2007, #9 Carbon monoxide poisoning can take place because Hemoglobin (Hgb) binds to carbon monoxide more tightly than oxygen. The reaction can be loosely described as follows: 1
