The decomposition of nitramide in aqueous solution at 25C NH,NO (aq) N2O(g) + H2O(1) is first order in NH,NO, with a rate constant of 4.70x10-5s! M If the initial concentration of NH,NO, is 0.336 M, the concentration of NH NO, will be after 30812 s have passed. The decomposition of hydrogen peroxide in dilute sodium hydroxide at 20C H,02(aq)-H,00) + % O2(g) is first order in H2O2 with a rate constant of 1.10-10-3 min! If the initial concentration of H,O, is 5.78*10-2 M, the concentration of H,O, will be 1.13x10-2 M after min have passed The rearrangement of cyclopropane to propene at 500 C (CH2) 3CH2CH=CH2 is first order in (CH2)3 During one experiment it was found that when the initial concentration of (CH)3 was 0.188 M, the concentration of (CH2), dropped to 2.14x102 M after 2418 s had passed. Based on this experiment, the rate constant for the reaction is
