Unformatted text preview: University of Southern California MASC 110L Final E. Goo December 6, 2006 Answer all questions. All questions are of equal value. 1. If a 136.51 g Al rod (specific heat capacity = 0.900 J/gC) is at 100.0 C and placed into 250.0 g of water at 21.8 C, what is the temperature of the system (rod + water) at equilibrium assuming no losses to the surroundings? 2. Consider the reaction of carbon monoxide with oxygen to produce carbon dioxide. 2 CO (g) + O 2 (g) 2 CO 2 (g) Estimate at what temperature will this reaction be spontaneous according to Gibbs Energy? 3. Consider the reaction: 2A + B C, and a kinetics study on this reaction yielded: [A] mol/L [B] mol/L Rate = mol/L/s 0.100 0.200 5.03 x 10-3 0.050 0.200 1.27 x 10-3 0.050 0.100 1.25 x 10-3 What is the value of the rate constant? 4. What is the molar solubility of AgCl (Ksp = 1.8 x 10-10 )? 5. What is the voltage for the Galvanic cell formed from these two half-reactions at these concentrations? Fe 2+ (aq) + 2e- Fe(s) ; [Fe2+] = 2.25 M E o = -0.44 V Ag + (aq) + e- Ag (s) [Ag+] = 1.55 x 10-4 M E o = 0.7994 V 6. A hydrocarbon contains 82.76 % C by mass. At 25 C and 750 mm Hg, 0.470 grams of this compound occupies a volume of 200 mL. of this compound occupies a volume of 200 mL....
