Inversion of cane sugar is an example of

Pseudo first order reaction

The correct answer is option 4. Pseudo first order reaction.

The inversion of cane sugar is an example of a Pseudo first order reaction.

Inversion of cane sugar: This process involves breaking down sucrose (cane sugar) into glucose and fructose.

Reaction order: Normally, the reaction rate depends on the concentration of the reactants raised to some power (order).

In cane sugar inversion, water is one of the reactants. However, water is usually present in a large excess during the reaction.

Pseudo first order: Because water concentration remains nearly constant, it can be treated as a constant factor in the rate equation. This effectively simplifies the reaction to follow first-order kinetics even though it's technically a second-order reaction (due to sucrose and water as reactants).

Therefore, the inversion of cane sugar exhibits pseudo-first order behavior.
