During conversion of ammonium carbamate into urea, presence of large excess of water______________?
Correct answer: B. Adversely affects the yield of urea
- A. Increases the yield of urea
- B. Adversely affects the yield of urea
- C. Reduces the evaporator load by diluting the urea solution
- D. Does not affect the yield of urea
Explanation
Urea formation from ammonium carbamate is an equilibrium reaction that produces water, so excess water shifts the equilibrium backward and lowers urea yield. It also increases the amount of solution requiring concentration.
