Write the reversible equation for the esterification and hydrolysis of glyceryl ethanoate
To write the reversible equations for the esterification and hydrolysis of glyceryl ethanoate, we need to first understand the reaction components and their changes.
Esterification:
Glyceryl ethanoate is formed by the reaction between glycerol and ethanoic acid in the presence of a catalyst such as sulfuric acid:
Glycerol + Ethanoic Acid ⇌ Glyceryl Ethanoate + Water
The reversible arrow (⇌) indicates that this reaction can proceed in both the forward and backward directions.
Hydrolysis:
Glyceryl ethanoate can be broken down into glycerol and ethanoic acid by a process called hydrolysis. This reaction occurs in the presence of an acid or a base, but for simplicity, we will consider hydrolysis in the presence of water:
Glyceryl Ethanoate + Water ⇌ Glycerol + Ethanoic Acid
Again, the reversible arrow indicates that this reaction can occur in both directions.
Therefore, the reversible equations for the esterification and hydrolysis of glyceryl ethanoate are:
Esterification: Glycerol + Ethanoic Acid ⇌ Glyceryl Ethanoate + Water
Hydrolysis: Glyceryl Ethanoate + Water ⇌ Glycerol + Ethanoic Acid
The reversible equation for the esterification of glyceryl ethanoate can be represented as follows:
Glycerol + Ethanoic Acid ⇌ Glyceryl Ethanoate + Water
And for the hydrolysis of glyceryl ethanoate, the reversible equation is:
Glyceryl Ethanoate + Water ⇌ Glycerol + Ethanoic Acid

You wil need to fill in the ester; I assume you know how to do that and I can't draw it on the board.
