Question

write the condition when a second order reaction becomes kinetically of first order

Open in App

Solution

Dear student,

A second order reaction can become first order if one of the reacting species is taken in excess such that its concentration remains practically unchanged during the course of reaction.
For ex: CH₃COOC₂H₅ + H₂O --> CH₃COOH + C₂H₅OH
If H₂O is taken in excess then, the reaction can be first order.
