In a study of the rearrangement of ammonium cyanate to urea in aqueous solution at 5C NH4NCO(aq)(NH2)2CO(aq) the following data were obtained Hint: It is not necessary to graph these data. (1) The observed half life for this reaction when the starting concentration is 0.380M is min and when the starting concentration is 0.190M is (2) The average (1/[NH4NCO])/t from t=0 min to t=299min is The average (1/[NH4NCO])/t from t=299min to t=896min is M1min1.M1min1. (3) Based on these data, the rate constant for this order reaction is M1min1
