Question

Complete the following reaction NH4CNO?

Answer 1

When dissolved in water, ammonium cyanate, NH4CNO, isomerizes to urea, H2NCONH2, in the following reaction.

NH4CNO(aq) → H2NCONH2(aq)

In this second-order reaction, the rate constant, k, is equal to 0.0597 L/mol·min. From an initial concentration of 0.153 M ammonium cyanate, calculate the concentration of ammonium cyanate after the reaction has progressed for 43.4 minutes.

Answer 2

Question - Complete the following reaction - NH4CNO on heating gives?

Answer - NH4CNO on heating gives urea.

The reaction is Wohler's synthesis. It was the first reaction in laboratory to produce organic compound namely urea from inorganic compound namely ammonium cyanate.

The reaction is isomerisation reaction.

The reaction of ammonium cyanate on heating is as follows-

NH4CNO --∆--> NH3 + HNCO --> (NH2)2CNO

∆ represents heating, HNCO is isocyanic acid, NH3 is ammonia, NH4CNO is ammonium cyanate and (NH2)2CNO is urea.
