After the excess sucrose has crystallized out, the rate of sucrose molecules leaving the surface of the crystals to be hydrated by water is less than the rate of sucrose molecules in water attaching to the surface of the crystals. true or false?

False

Explanation:

Once the process of the crystallization is complete, then the process of crystallization and the process of hydration both comes in picture.

The molecules leaving the crystal are hydrated by the water and same is the number of the molecules in water, attaches to the crystal.

The both processes exist in dynamic equilibrium where the rate of the crystallization is equal to the rate of the hydration.

So, given statement is false.
