Question

Role of H2SO4 in esterification reaction

Answer 1

Esterification is a relatively slow process at room temperature and does not proceed to completion. Concentrated sulfuric acid is used as a catalyst, and has a dual role: Speeds up the reaction. Acts as a dehydrating agent, forcing the equilibrium to the right and resulting in a greater yield of ester.

Answer 2

H2 SO4 act as dehydrating agent.l in esterification reaction.
