908. As a result of dissolution in water, ammonium cyanate turns into urea, NH4NCO → CO(NH2)2. Determine the kinetic order, the rate constant and the initial concentration of NH4NCO from the following data (C is the current concentration of NH4NCO; t is the time after the preparation of the solution):
t, min 114 405 662 1388 1780 2790
С, mol/l 0.0213 0.0155 0.0124 0.0079 0.0066 0.0046
