Why does the increase of an area of a solid cause an increase in the rate of dissolving?

The increase in the surface area of a solid enhances the rate of dissolving because it exposes more particles of the solid to the solvent. When more surface area is available, there are more interactions between the solid and solvent molecules, leading to a greater number of collisions and faster dissolution. This increased interaction accelerates the process by which the solid breaks apart and enters the solution. Therefore, a larger surface area generally results in a quicker rate of dissolving.
