2. The isomerization of ammonium cyanate (NH₂CNO) to urea follows the second-order kinetics with a rate constant of 9.9 X 10-4 /M.s at 25°C. H₂NCONH₂ (aq) NH4CNO(aq) → a) From an initial concentration of 0.24 M NH4CNO, how much of it (in M) remains after 15.0 minutes? b) What is the half-life (in minutes) for the reaction?
