In a study of the rearrangement of ammonium cyanate to urea in aqueous solution at 50 °C
NHẠNCO(aq)→(NH2)½CO(aq)
the concentration of NH,NCO was followed as a function of time.
It was found that a graph of 1/[NH4NCO] versus time in minutes gave a straight line with a
slope of 1.44×102 Ml min-1 and a y-intercept of 0.980 M-!.
Based on this plot, the reaction is
order in NH4NCO and the rate constant for the
reaction is
M1 min-1.
