Q: The size of the solute particles determines the rate of what?


Read this paragraph and choose the correct option from the provided answers:

The rate at which a solute dissolves depends upon the size of the solute particles. Dissolving is a surface phenomenon since it depends on solvent molecules colliding with the outer surface of the solute. A given quantity of solute dissolves faster when it is ground into small particles than if it is in the form of a large chunk because more surface area is exposed. The packet of granulated sugar exposes far more surface area to the solvent and dissolves more quickly than the sugar cube.

 Choices:

- merging

- extracting

- solution

- dissolving


A:
dissolving
