Acetic acid and ethanol react to form ethyl acetate and water, like this: \[ \mathrm{HCH}_{3} \mathrm{CO}_{2}(a q)+\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}(a q) \rightarrow \mathrm{C}_{2} \mathrm{H}_{5} \mathrm{CO}_{2} \mathrm{CH}_{3}(a q)+\mathrm{H}_{2} \mathrm{O}(i) \] Imagine 129. mmol of \( \mathrm{HCH}_{3} \mathrm{CO}_{2} \) are removed from a flask containing a mixture of \( \mathrm{HCH}_{3} \mathrm{CO}_{2}, \mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}_{2} \mathrm{C}_{2} \mathrm{H}_{5} \mathrm{CO}_{2} \mathrm{CH}_{3} \) and \( \mathrm{H}_{2} \mathrm{O}_{2} \) at equilibrium, and then answer the following questions.
