Question

Quizplus · Accepted Answer

This reaction appears to be an esterification reaction, where a carboxylic acid and an alcohol react to form an ester and water. Esters typically require heat and a catalyst to proceed at a reasonable rate, with both acid and base catalysts being commonly used. In this case, since the reactants include a carboxylic acid, adding an acid catalyst (such as sulfuric acid) would be beneficial. Additionally, heating the reaction would increase the rate of the reaction. Therefore, the best option is to heat the reaction and add an acid catalyst (choice D).
