Acid hydrolysis of sucrose is a

Options

  1. Apseudo first order reaction
  2. Bzero order reaction
  3. Csecond order reaction
  4. Dunimolecular reaction.

Correct answer

A. pseudo first order reaction

Step-by-step solution

It is an example of pseudo unimolecular reaction where molecularity 2 but order of reaction is one. Rate =k[ Sugar ] [ H ₂ O ] In the reaction, water is present in excess and its concentration is taken to be constant, thus the reaction becomes independent of [ H ₂ O ] and is pseudo first order.
