Solution

In the presence of acid catalyst, ethanoic acid reacts with ethanol and ethyl ethanoate ester is produced.

Explanation:

\[\ce{\underset{(Ethanoic acid)}{CH3-COOH} + \underset{(Ethanol)}{CH3-CH2-OH} ->[Acid][Catalyst] \underset{(Ethyl ethanoate)}{CH3-COO-CH2-CH3} + \underset{(Water)}{H2O}}\]
