We are asked to calculate the mass of urea is produced per minute by this reaction assuming 100% yield
2NH3(g) + CO2(g) → H2NCONH2(s) + H2O(g)
Step 1. Calculate moles per minute of each
n = 1105.27 mol/min NH3
n = 663.16 mol/min CO2
Step 2. Simultaneously calculate the theoretical yield and identify the limiting reactant.
Use both to calculate for H2NCONH2
Molar mass H2NCONH2 = 60.07 g/mol
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 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?
