Waec Model Questions Vol1 2025 Chemistry Question 15
Practice objective / multiple choice question 15 from the 2025 Waec Model Questions Vol1 Chemistry examination.
In a 1.00 L flask at 25 °C, 0.500 mol of acetic acid (CH₃COOH) is mixed with 0.500 mol of ethanol (CH₃CH₂OH). They undergo esterification: CH₃COOH + CH₃CH₂OH ⇌ CH₃COOCH₂CH₃ + H₂O, with an equilibrium constant Kc = 4.0 at this temperature. Assuming ideal behaviour, (a) determine the equilibrium concentration of ethyl acetate, and (b) calculate the percent conversion of acetic acid.
