1. Determine the concentration of CO(g) in water at 25 ºC and 0.010 atm. given that the Henry’s law constant for this system is 5.80 x 104 atm. 2. What is the ratio of the solubilities of N2 and O2 in water at 100 ºC given that K2/(atm.) = 12.6 x 104 for N2 and 7.01 x 104 O2? Assume that P(N2) = 0.80 atm. and P(O2) = 0.20 atm. 3. A “100 proof” solution of ethanol in water consists of 50.00 mL of C2H4OH(l) and 50.00 mL of H2O(l) mixed at 15.56 ºC. The density of the solution is 0.9344 g/mL, that of pure H2O is 1.00 g/mL and that of C2H5OH is 0.7939 g/mL. Is this solution ideal? 4. Assuming that C6H6 and C6H5CH3 form ideal solutions, calculate ΔG, ΔH and ΔS at 25 ºC for the addition of 1.00 mol of C6H6 to an infinitely large sample of solution with χ(C2H6) = 0.35. The vapor pressure of C6H6 at 25 ºC is 0.153 bar. 5. At 25 ºC,Sº/J.K-1.mol-1 = 269.2for C6H6(l) and 310.7 for C6H5CH3. What is the value of Sº for a solution prepared by mixing 0.50 molC6H6 with 1.50 mol C6H5CH3? 6. Derive the integrated rate law for an nth-order reaction for the chemical equation A → P, where n ≠ 1. Repeat the derivation for n = 1. 7. Use the following half-life data for the decomposition of N2O(g) at 1030 K to determine the order of reaction and the rate constant: t½/s 212 255 470 860 P(N2O)0/torr 360 290 139 52.5 8. Given τ = 23 µs and K = 1.0 x 103,determine k1 and k2 for the following reaction 9. The rate constant for nonionic reaction that occurs by a bimolecular collision in dilute solution is given by kD = aRT/3η where a= 4 for collision between like molecules, a = 8 for collisions between unlike molecules, and η is the coefficient of viscosity of the solvent. Calculate kD for a reaction between unlike molecules in water at 25 ºC. For water, η = 0.900 x 10-3Pa.s at 25 ºC 10. The rate constant for the bimolecular collision reaction: H3O+(aq) + OH-(aq) → 2H2O(l) is 1.3 x 1011L.mol-1.s-1. Determine r(H3O+ + r(OH- for the diffusion-controlled reaction given D(H3O) = 9.31 x 10-9 m2.s-1 and D(OH-) = 5.30 x 10-9 m2.s-1 at 25 ºC. Interpret the results. 11. The following data were obtained for an enzyme that catalyzes the reaction S → P. The substrate concentrations have been spaced to allow use of any of the linear plots. Plot the data and determine Km and Vmax [S] 8.33 x 10-6 1.00 x 10-5 1.25 x 10-5 1.67 x 10-5 2.00 x 10-5 2.5x10-5 3.33 x 10-5 4.00 x10-5 5.00 x 10-5 6.00 x 10-5 -5 8.00x10 1.00 x 10-4 2.00 x 10-4 v 13.8 16.0 19.0 23.6 26.7 30.8 36.3 40.0 44.4 48.0 53.4 57.1 66.7 Units of [S} and v are; M and nmoles/L-min, respectively. 12. The following data were obtained for quenching of acridone in water at 26 ºC. Use τo = 17.6 nsec. KNO3 is used to maintain a constant ionic strength, and does not quench the fluorescence of acridone. M, KI M, KNO3 I0/I 0 0.04 1.10 1.06 11.01 4.64 0.10 1.00 10.59 0.20 0.90 23.0 0.30 0.80 37.2 0.50 0.60 68.8 0.80 0.30 137

Explanation & Answer

Kindly see attached file with step by step solution of the different problems. I've included a pdf version as well in case you face any problem when trying to see the equations used.Note that in question 12 only data were provided but there was no real question. I've used the data to evaluate the kinetics of the quenching effect and compare it to the fluorescence emission. If the question was any other please ...
