Chapter 5, Problem 62E

Urea ${\text{(H}}_{\text{2}}{\text{NCONH}}_{\text{2}}\text{)}$ is used extensively as a nitrogensource in fertilizers. It is produced commercially fromthe reaction of ammonia and carbon dioxide:

${\text{2NH}}_{\text{3}}\text{(}g{\text{)+CO}}_{\text{2}}\text{(}g\text{)}\underset{\text{pressure}}{\overset{\text{Heat}}{\to }}{\text{H}}_{\text{2}}{\text{NCONH}}_{\text{2}}\text{(}s{\text{)+H}}_{\text{2}}\text{O(}g\text{)}$

Ammonia gas at 223°C and 90. atm flows into a reactorat a rate of 500. L/min. Carbon dioxide at 223°C and45 atm flows into the reactor at a rate of 600. L/min.What mass of urea is produced per minute by this reactionassuming 100% yield?
