Question

Give an example pseudo first order reaction.

Answer 1

CH3COOC2H5 + H2O--------) CH3COOH + C2H5OH

Answer 2

Hey !!

Example :- The inversion of cane sugar is a bimolecular reaction but it is a first order reaction as concentration of H₂O is quite large and does not change appreciably.

   

                     C₁₂H₂₂O₁₁ + H₂O --H⁺--> C₆H₁₂O₆ + C₆H₁₂O₆

                     Rate = k [C₁₂H₂₂O₁₁]

                         OR

Acid Hydrolysis of ethyl acetate  

      CH₃COOC₂H₅ + H₂O --H⁺--> CH₃COOH + C₂H₅OH

        Rate ∝ [CH₃COOC₂H₅] as H₂O is in excess.

Hope it helps you !!
