A carboxylic acid ester is prepared commonly by reacting a carboxylic acid with excess of an alcohol in the presence of a small quantity of a strong acid such as conc. H ₂ SO ₄ as a catalyst. The reaction is reversible and generally the equilibrium constant for the esterification is close to 1 . As it is a reversible reaction, different methods are used to increase the yield of ester. It is established that the mecha
Options
- AWhen esterification is carried out using molar ratio of acid and alcohol as 1:10, the yield of the ester with
- BThe function of conc. H ₂ SO ₄ is also to increase the free energy change of the reaction and thereby increasi
