Problem 6 . The following reactions and rates account for the decomposition of N2O5: N2O5 NO2 + NO3 = ka [N2O5] NO2 + NO3 N2O5 = k'a [NO2][NO3] NO2 + NO3 NO2 + O2 + NO = kb [NO2][NO3] NO + NO3 2 NO2 = kc [NO][NO3] Clearly, some of these equations involve intermediates.

a (6 points). Give the balanced overall reaction scheme for the decomposition of N2O5, where N2O5 is the only species on the left. Thus: x N2O5 ... Your reaction scheme should show all intermediates and final product(s); of course, the scheme has to be balanced.

b (2 points). Give the balanced overall equation for the decomposition of N2O5, where N2O5 is the only species on the left. Thus: x N2O5 ... Your equation should not contain any intermediates, but only N2O5 and the final product(s).

c (7 points). The rate of the N2O5 decomposition is given by = k [N2O5]. Express k as a function of ka, and/or k'a, and/or kb, and/or kc. Hint: use your answer to 6a and the steady state approximation.
