20 ~mL of acetic acid reacts with 20 ~mL of ethyl alcohol to form ethyl acetate. The density of acid and alcohol are 1 ~g / mL and 0.7 ~g / mL respectively. The limiting reagent in this reaction is

Step-by-step solution

Mass of 20 ~mL of acetic acid =20 1=20 ~g Mass of 20 ~mL of ethyl alcohol =20 0.7=14 ~g For the reaction, 60 ~g CH ₃ COOH + 46 ~g C ₂ H ₅ OH - H ₂ O CH ₃ COOC ₂ H ₅ 60 ~g of acetic acid requires =46 ~g of ethyl alcohol 20 ~g of acetic acid requires = 46 60 20=15.3 ~g of ethyl alcohol Therefore, ethyl alcohol is the limiting reagent.
