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 0.790 M, the concentration of N2O dropped to 0.103 M after 5.21×10^3 seconds had passed. Based on these data, the rate constant for the reaction is _____________ M-1 s-1.
