Urea (H2NCONH2) is used extensively as a nitrogen source in fertilizers. It is produced commercially from the reaction of ammonia and carbon dioxide:
2NH3 (g) + CO2 (g) H2NCONH2 (s) + H2O (g)
Ammonia gas at 223oC and 90 atm flows into a reactor at a rate of 500 L/min. Carbon dioxide at 223oC and 45 atm flows into the reactor at a rate of 600 L/min. What mass of urea is produced per minute by this reaction assuming 100% yield?
