For the gas phase decomposition of dinitrogen pentoxide at 335 K: 2 N2O5 -> 4 NO2 + O2 the average rate of disappearance of N2O5 over the time period from t = 0 s to t = 113 s is found to be 2.22×10^-4 M s^-1. The average rate of formation of NO2 over the same time period is M s^-1.

For the gas phase decomposition of nitrogen dioxide at 383°C: 2 NO2(g) → 2 NO(g) + O2(g) The average rate of disappearance of NO2 over the time period from t = 0 s to t = 7.35 s is found to be 2.61×10-2 M s-1. What is the average rate of appearance of O2 over the same time period? M s-1.

The decomposition of nitrous oxide at 565 °C N2O(g) → N2(g) + ½ O2(g) is second order in N2O. In one experiment, when the initial concentration of N2O was 1.21 M, the concentration of N2O dropped to 0.140 M after 4.21×10^3 seconds had passed. Based on these data, the rate constant for the reaction is __________ M-1 s-1.
