The rearrangement of ammonium cyanate to urea in aqueous solution at $50C$

$N{H}_4$NCO$(aq)(N{H}_2{)}_{2}CO(aq)$

is second order in

$N{H}_4$NCO with a rate constant of $0\mathrm{.}0110$

$\frac{1}{M*min}.$

If the initial concentration of $N{H}_4$NCO is $0\mathrm{.}823M,$ the concentration of $N{H}_4$NCO will be $M$ after $3,08$ minutes have passed.
