Mention two functions performed by the concentrated sulfuric acid in the reaction ​

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.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
