In a study of the rearrangement of ammonium cyanate to urea in aqueous solution at 50 °C NH4NCO(aq)- >(NH2)2CO(aq) the concentration of NH4NCO was followed as a function of time. -1 -1 It was found that a graph of 1/[NH₂NCO] versus time in minutes gave a straight line with a slope of 1.50×10¹² M¹ min Based on this plot, the reaction is order in NH4NCO and the rate constant for the reaction is and a y-intercept of 2.29 M M₁1¹. -1 M1¹ min¹.
Use the References to access important values The rearrangement of ammonium cyanate to urea in aqueous solution at 50 °C NH4NCO (aq) → (NH₂)2CO (aq) is second order in NHANCO. In one experiment, when the initial concentration of NH4NCO was 0.320 M, the concentration of NH4NCO dropped to 7.68 x 10-2 M after 647 minutes had passed. Based on these data, the rate constant for the reaction is M¹ min-1 needed for this question.
