6. Based on work by S.S. Brown et al. [Science, 311, 67-70 (2006)], N205, formed in the presence of NO2 and N03, is involved in nocturnal radical chemistry in the atmosphere, establishing equilibrium with the precursor radical species via: NO2 (G) + NO3 (9) 205 (9) Using the thermodynamic data for P°, T = 298.15 K: %3D AG, (kJ · mol-1) | s'(J · mol-1 . K-1) 240.1 AH (kJ mol-1) NO2 (g) N03 (9) N205 (9) 51.3 33.2 . 258.40 107.67 64.4 355.7 117.1 13.3 a. State whether the equilibrium position will shift towards reactants or products as the pressure is decreased. Justify your prediction. 5 points b. State whether the equilibrium position will shift towards reactants or products as the temperature is decreased. Justify your prediction. 5 points C. Calculate Kg at T = 298.15 K and at T = 283.15 K. 20 points d. Denver's lab partner sets up a constant volume, T = 283.15 K container into which he added N,0g with an initial pressure of 1 × 10-7 bar = 10-2 Pa. What will be the equilibrium ratio of N20s: NO,? Treat the gases as idea. 20 points %3D 2
