Is the acid-catalyzed hydrolysis of acetamide a reversible or an irreversible reaction?

Acid catalyzed hydrolysis of acetamide is irreversible

Explanation:

Acid-catalyzed hydrolysis of acetamide is an irreversible process.

All the steps in the hydrolysis of acetamide are reversible except the penultimate step.

Because in the penultimate step, an irreversible acid-base reaction occurs between acetic acid and ammonia. Equilibrium position of this acid-base reaction lies almost completely towards right. Therefore, this irreversible step alone makes hydrolysis of acetamide irreversible as a whole.

Mechanism of hydrolysis has been shown below.

fe 55.85 g/mol and h2o 18.02 g/mol.
