A mixture contains \(0.050\ \text{mol}\) of 2‑butanol and \(0.030\ \text{mol}\) of acetic acid. They are allowed to react at \(25^{\circ}\text{C}\) in the presence of a catalytic amount of sulphuric acid. The esterification equilibrium constant is \(K = 4.0\times10^{-3}\) for the reaction\n\(\displaystyle \mathrm{CH_3CH_2CH(OH)CH_3 + CH_3COOH \rightleftharpoons CH_3COOCH_2CH_2CH_2CH_3 + H_2O}.\)\nCalculate the maximum amount (in moles and grams) of butyl acetate that can be formed at equilibrium and state which reactant remains the limiting reagent after equilibrium is reached. (Molar mass of butyl acetate = 116.16 g·mol⁻¹).

Answer Options

Correct Answer A. 0.00230 mol (≈0.27 g) of butyl acetate; acetic acid remains the limiting reagent.
B. 0.00230 mol (≈0.27 g) of butyl acetate; 2‑butanol remains the limiting reagent.
C. 0.00115 mol (≈0.13 g) of butyl acetate; 2‑butanol remains the limiting reagent.
D. 0.00460 mol (≈0.53 g) of butyl acetate; acetic acid remains the limiting reagent.
Correct Answer
A
Correct Option:
0.00230 mol (≈0.27 g) of butyl acetate; acetic acid remains the limiting reagent.
