Question

Inversion of sucrose in presence of dilute acid is said to be pseudo first order reaction.

1. Why is it said to be so?

2. Give another example of pseudo order reaction.

Answer 1

1.

The rate depends only on the concentration of sucrose and it is independent of the concentration of water. Thus, the reaction appears to be of second order but actually follows first order kinetics,

2. Hydrolysis of ester in presence of acid.
