Answer : Option B
Explanation :
Urea is prepared by the chemical reactions of Ammonia and carbon dioxide. This is a two step process where the ammonia and carbon dioxide react to form ammonium carbamate which is then dehydrated to urea. In the process, ammonia and carbon dioxide are fed to the synthesis reactor which operates around 180-210oC and 150 bar pressure.
