Ethanol reacts with ethanoic acid to produce ethyl ethanoate in the reaction shown below. $\text{C}_2\text{H}_5\text{OH}(l) + \text{CH}_3\text{CO}_2\text{H}(l) \rightleftharpoons \text{CH}_3\text{CO}_2\text{C}_2\text{H}_5(l) + \text{H}_2\text{O}(l)$ $\Delta H^\circ = -6\,\text{kJ mol}^{-1}$ 9.2 g of ethanol, 12 g of ethanoic acid and 8.8 g of ethyl ethanoate are combined and left at 298 K until equilibrium is attained. $(M_r:\ \text{C}_2\text{H}_5\text{OH},\ 46;\ \text{CH}_3\text{CO}_2\text{H},\ 60;\ \text{CH}_3\text{CO}_2\text{C}_2\text{H}_5,\ 88)$ The analysed equilibrium mixture is shown to have 4.8 g of ethanoic acid. The experiment is then carried out again at 323 K. Which statements are true?
- A1, 2 and 3
- B1 and 2 only
- C2 and 3 only
- D1 only
