Glacial acetic acid (CH\(_3\)COOH, molar mass 60.05 g mol\(^{-1}\)) reacts with ethanol (C\(_2\)H\(_5\)OH, molar mass 46.07 g mol\(^{-1}\)) according to the equation \(\mathrm{CH_3COOH + C_2H_5OH \rightarrow CH_3COOC_2H_5 + H_2O}\). If 5.0 g of acetic acid are mixed with 6.0 g of ethanol and the reaction yields 6.5 g of ethyl acetate, determine: (a) the limiting reagent, (b) the theoretical mass of ethyl acetate, (c) the percent yield, and (d) the mass of excess ethanol remaining unreacted.

Answer Options

Correct Answer A. Limiting reagent: acetic acid; Theoretical mass: 7.34 g; Percent yield: 89%; Excess ethanol: 2.16 g
B. Limiting reagent: ethanol; Theoretical mass: 7.34 g; Percent yield: 89%; Excess ethanol: 0.00 g
C. Limiting reagent: acetic acid; Theoretical mass: 8.10 g; Percent yield: 95%; Excess ethanol: 0.90 g
D. Limiting reagent: ethanol; Theoretical mass: 6.80 g; Percent yield: 78%; Excess ethanol: 1.20 g
Correct Answer
A
Correct Option:
Limiting reagent: acetic acid; Theoretical mass: 7.34 g; Percent yield: 89%; Excess ethanol: 2.16 g
