CBSE Class 12 Chemistry Notes: Chemical Kinetics – Dehydration of Oxalic Acid & Hydrolysis of Ethyl Acetate

Dehydration of oxalic acid

In the presence of concentrated H₂SO₄, oxalic acid undergoes dehydration as follows:

Like H₂O₂, the amount of oxalic acid present at any time can be found by titrating against KMnO₄ solution. Hence the same formula as found for decomposition of H₂O₂ is applicable.

Hydrolysis of Ethyl acetate:

In this reaction, acetic acid is one of the products, the amount of which can be found by titrating against standard NaOH solution. But being an acid-catalyzed reaction, the acid is present originally as catalyst, also reacts with NaOH solution.

Substituting the values of a and (a – x) from equations (vi) and (vii) in the first order equation, we get
