The gas phase decomposition of nitrogen dioxide at 383 °C NO2(g)NO(g) + ½ O2(g) is second order in NO2. In one experiment, when the initial concentration of NO2 was 0.449 M, the concentration of NO2 dropped to 5.84×10-2 M after 20.6 seconds had passed. Based on these data, the rate constant for the reaction is_______ M-1 s-1?
