The rearrangement of cyclopropane to propene at 500 C (CH2)3 CH2CH=CH2 is first order in (CH2)3 with a rate constant of 6.70x10-45-1. If the initial concentration of (CH2)3 is 0.154 M, the concentration of (CH2)3 will be M after 2831 s have passed. Submit Answer Retry Entire Group 8 more group attempts remaining The decomposition of nitramide in aqueous solution at 25 C NH2NO2(aq)->N20(g) + H2O(1) is first order in NH2NO, with a rate constant of 4.70x10-5 5-1 If the initial concentration of NH NO2 is 0.774 M, the concentration of NH2NO2 will be 0.114 M after s have passed The decomposition of hydrogen peroxide in dilute sodium hydroxide at 20 C H2O2(aq)->H2O(l) + 1/ 2O2(g) is first order in H202 During one experiment it was found that when the initial concentration of H2O2 was 3.78*10-2 M, the concentration of H2O2 dropped to 4.35*10-3 M after 1252 min had passed. Based on this experiment, the rate constant for the reaction is min-1
