In a 1.00 L solution, 0.30 mol of acetic acid (\(CH_3COOH\), \(K_a = 1.8 \times 10^{-5}\)) is mixed with 0.20 mol of ethanol (\(C_2H_5OH\)). The esterification reaction\n\n\(CH_3COOH + C_2H_5OH \rightleftharpoons CH_3COOC_2H_5 + H_2O\)\n\nhas an equilibrium constant \(K = 4.0\) at 25 °C. Assuming the reaction reaches equilibrium, what percentage of the initial acetic acid is converted to ethyl acetate?

Answer Options

Correct Answer A. ≈ 52 % of the acetic acid is converted to ethyl acetate
B. ≈ 38 % of the acetic acid is converted to ethyl acetate
C. ≈ 65 % of the acetic acid is converted to ethyl acetate
D. ≈ 10 % of the acetic acid is converted to ethyl acetate
Correct Answer
A
Correct Option:
≈ 52 % of the acetic acid is converted to ethyl acetate
