The gas phase decomposition of hydrogen peroxide at 400 °C H2O2(g)—>H2O(g) + 42 O2(g) is second order in H2O2. In one experiment, when the initial concentration of 1,02 was 0.153 M, the concentration of H2O2 dropped to 2.51x10-2 M after 36.1 seconds had passed. Based on these data, the rate constant for the reaction is M's-1 The gas phase decomposition of nitrogen dioxide at 383 °C NO2(g)—>NO(g) + 12 02(g) is second order in NO, with a rate constant of...
