Acid hydrolysis of sucrose is a

Options

A. pseudo firs order reaction
B. zero order reaction
C. second order reaction.
D. unimolecular raction.

Answer

A

Explanation

It is an example of pseudo unimolecular reaction where molecularity `ge` 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 .
