The ester ethyl ethanoate is hydrolysed slowly in the presence of excess water and a strong acid catalyst, according to the equation shown below: CH3COOC2H5(l) + H2O(l) ⇌ CH3COOH(l) + C2H5OH(l)
A student obtained some data from which he deduced the amount of ethanoic acid in the reaction mixture over the first 300 minutes of this reaction. a Describe how the student could obtain these data.
