Which of the following react to produce urea ?

Options

A. Ammonium Chloride + Calcium sulphate
B. Carbon dioxide + Ammonia
C. Acetic acid + Ammonia
D. Methane + Carbon Monoxide

Answer

B

Explanation

For use in industry, urea is produced from synthetic ammonia and carbon dioxide. The process consists of two main equilibrium reactions: (i) the fast exothermic reaction of liquid ammonta with gaseous carbon dioxide to form ammonium carbamate, and (11) urea conversion: the slower endothermic decomposition of ammonium carbamate into urea and water.
