Hemoglobin (Hb) binds to both oxygen and carbon monoxide. When the carbon monoxide replaces the oxygen in an organism, the following reaction occurs: HbO2(aq)+CO(g)HbCO(aq)+O2(g) At 37C, K is about 200. When equal concentrations of HbO2 and HbCO are present, the effect of CO inhalation is fatal. Assuming PO2=0.21atm, what is PCO when [ HbO2 ]=[ HbCO ]?
Monochloroethane (C2H5Cl) can be produced by the direct reaction of ethane gas (C2H6) with chlorine gas or by the reaction of ethylene gas (C2H4) with hydrogen chloride gas. The second reaction gives almost a 100% yield of pure C2H5Cl at a rapid rate without catalysis. The first method requires light as an energy source or the reaction would not occur. Yet G for the first reaction is considerably more negative than G for the second reaction. Explain how this can be so.
Consider the reaction H2(g)+Br2(g)2HBr(g) where H = 103.8 kJ/mol. In a particular experiment, equal moles of H2(g) at 1.00 atm and Br2(g) at 1.00 atm were mixed in a 1.00-L flask at 25C and allowed to reach equilibrium. Then the molecules of H2 at equilibrium were counted using a very sensitive technique, and 1.10 1013 molecules were found. For this reaction, calculate the values of K, G, and S.
5.12. True or false: If all the partial pressures of reactants and products drop by half, the value of Q drops by half. Give an example of a chemical reaction to support your answer.
For the following reaction C(s)+2H2(g)CH4(g) K=0.26 at 1000C (3 significant figures). What is the equilibrium constant at 750C (3 significant figures)?
Silicon forms a series of compounds analogous to the al-kanes and having the general formula SinH2n+2. The first of these compounds is silane, SiH4, which is used in the electronics industry to produce thin ultrapure silicon films. SiH4(g) is somewhat difficult to work with because it is py-ropboric at room temperature—meaning that it bursts into flame spontaneously when exposed to air. (a) Write an equation for the combustion of SiH4(g). (The reaction is analogous to hydrocarbon combustion, and SiO2 is a solid under standard conditions. Assume the water produced will be a gas.) (b) Use the data from Appendix E to calculate ? for this reaction. (c) Calculate G and show that the reaction is spontaneous at 25°C. (d) Compare G for this reaction to the combustion of methane. (See the previous problem.) Are the reactions in these two exercises enthalpy or entropy driven? Explain.
Why are there no changes specified for Ni in Exercise 13.61, part (f)? What property of Ni does change?
For the decomposition of Ag2O: 2Ag2O(s)4Ag(s)+O2(g)(a) Obtain an expression for G as a function of temperature. Prepare a table of G values at 100 K intervals between 100 K and 500 K. b) Calculate the temperature at which G =0.
If wet silver carbonate is dried in a stream of hot air. the air must have a certain concentration level of carbon dioxide to prevent silver carbonate from decomposing by the reaction Ag2CO3(s)Ag2O(s)+CO2(g) H for this reaction is 79.14 kJ/mol in the temperature range of 25 to 125C. Given that the partial pressure of carbon dioxide in equilibrium with pure solid silver carbonate is 6.23 103 torr at 25C, calculate the partial pressure of CO2 necessary to prevent decomposition ofAg2CO3 at 110C. (Hint: Manipulate the equation in Exercise 79.)
Describe how you would expect the spontaneity (G) for each of the following reactions to behave with a change of temperature. a Phosgene, COCl2, the starting material for the preparation of polyurethane plastics, decomposes as follows: COCl2(g)CO(g)+Cl2(g) b Chlorine is added to ethylene to produce dichloroethane, a solvent: Cl2(g)+C2H4(g)C2H4Cl2(l)
Consider the formation of HI(g) from H2(g) and I2(g). H2(g)+I2(g)2HI(g) For this reaction, K at 333C is 98, while K at 527C is 62.5. Find S for I2(g) at 527C.
