Urea (H2NCONH2) is used extensively as a nitrogen source in fertilizers. It is produced commercially from the reaction of ammonia and carbon dioxide.
2 NH3(g) + CO2(g) H2NCONH2(s) + H2O(g)
Ammonia gas at 223°C and 90. atm flows into a reactor at a rate of 660. L/min. Carbon dioxide at 223°C 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? Find _____g/min
