Acetic acid (\(CH_3COOH\), M = 60.05 g mol⁻¹) reacts with ethanol (\(C_2H_5OH\), M = 46.07 g mol⁻¹) in the presence of \(H_2SO_4\) to form ethyl acetate and water. 5.0 g of acetic acid is mixed with 4.6 g of ethanol and the reaction is allowed to proceed to completion. (a) Which reactant is the limiting reagent? (b) What is the maximum mass of ethyl acetate that could be formed? (c) If 3.2 g of ethyl acetate is actually obtained, calculate the percentage yield. (d) How many grams of water are formed in the reaction?

Answer Options

Correct Answer A. Limiting reagent: acetic acid; Theoretical mass: 7.34 g; Percent yield: 43.6 %; Water formed: 1.50 g
B. Limiting reagent: acetic acid; Theoretical mass: 7.34 g; Percent yield: 55.0 %; Water formed: 1.50 g
C. Limiting reagent: ethanol; Theoretical mass: 6.20 g; Percent yield: 51.6 %; Water formed: 1.20 g
D. Limiting reagent: acetic acid; Theoretical mass: 8.10 g; Percent yield: 39.5 %; Water formed: 1.70 g
Correct Answer
A
Correct Option:
Limiting reagent: acetic acid; Theoretical mass: 7.34 g; Percent yield: 43.6 %; Water formed: 1.50 g
