Neco 2024 Chemistry Question 5
Practice objective / multiple choice question 5 from the 2024 Neco Chemistry examination.
Acetic acid (CH₃COOH) has \(K_a = 1.8\times10^{-5}\). It reacts with ethanol to give ethyl acetate and water. At 298 K the equilibrium constant for the esterification (in concentration terms) is \(K = 4.5\). If 0.10 mol of acetic acid and 0.10 mol of ethanol are placed in 1.00 L of water with no ester initially present, calculate the fraction of the original acetic acid that is converted to ethyl acetate at equilibrium (give the answer as a decimal to two significant figures).
