    The decomposition of nitramide in aqueous solution at 25 °C NH2NO2(aq)------->N2O(g) + H2O(l) is first order in NH2NO2. During one experiment it was found that when the initial concentration of NH2NO2 was 0.458 M, the concentration of NH2NO2 dropped to 0.117 M after 21860 s had passed. Based on this experiment, the rate constant for the reaction is _________s-1.

    In a study of the decomposition of nitramide in aqueous solution at 25 degree C NH_2NO_2(aq) rightarrow N_2O(g) + H_2O(1) the concentration of NH_2NO_2 was followed as a function of time. It was found that a graph of ln[NH_2NO_2] versus time in seconds gave a straight line with a slope of -6.72 times 10^-5 s^-1 and a y-intercept of -0.863. Based on this plot, the reaction is order in NH_2NO_2 and the rate constant for the reaction is s^-1.
