Ammonium cyanate (NH4CNO) in water solution gradually isomerizes intourea (H2NCONH2), according to the reaction NH4CNO (aq) à H2NCONH2 (aq). Thisreaction obeys a second order rate law, with a rate constant k = 7.0 x 10-2 L/(mol min). If a 0.50 M solution of ammonium cyanate is prepared at some initial time, t=0, what concentration of ammonium cyanate is left after 100 minutes?
