Neco 2023 Chemistry Question 46
Practice objective / multiple choice question 46 from the 2023 Neco Chemistry examination.
An esterification reaction between acetic acid (\( \text{CH}_3\text{COOH} \)) and ethanol (\( \text{C}_2\text{H}_5\text{OH} \)) is carried out using 5.0 g of acetic acid (M = 60.05 g·mol\(^{-1}\)) and 4.6 g of ethanol (M = 46.07 g·mol\(^{-1}\)). Only 80 % of the ethanol is available for reaction because the remaining 20 % acts as solvent. After reflux, 5.2 g of ethyl acetate (\( \text{CH}_3\text{COOCH}_2\text{CH}_3 \), M = 88.11 g·mol\(^{-1}\)) is isolated. Assuming the reaction follows the stoichiometry 1 : 1 and that the only loss is due to incomplete reaction, calculate the percentage yield of ethyl acetate.
