Urea (H 2 NCONH 2 ) is used extensively as a nitrogen source in fertilizers. It is produced commercially from the reaction of ammonia and carbon dioxide: 2 NH 3 ( g ) + CO 2 ( g ) → Pressure Heat H 2 NCONH 2 ( s ) + H 2 O ( g ) Ammonia gas at 223°C and 90. atm flows into a reactor at a rate of 500. 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?
