Igcse Model Questions Vol1 2025 Chemistry Question 18
Practice objective / multiple choice question 18 from the 2025 Igcse Model Questions Vol1 Chemistry examination.
Propanoic acid (\(\mathrm{CH_3CH_2COOH}\)) reacts with ethanol (\(\mathrm{CH_3CH_2OH}\)) in an acid‑catalysed esterification: \(\mathrm{CH_3CH_2COOH + CH_3CH_2OH \rightleftharpoons CH_3CH_2COOCH_2CH_3 + H_2O}\). Initially, 0.050 mol of propanoic acid and 0.030 mol of ethanol are mixed, and the equilibrium constant at 25 °C is \(K = 4.0\) (based on concentrations). Calculate the amount (in moles, to three significant figures) of ethyl propanoate formed at equilibrium.
