Answer:

The correct option of the first option

Explanation:

Dissolution of a solute in a solution is the process in which the solute interacts with the solvent leading to the disappearance of the solute to form a solution. Rate of dissolution is primarily affected by three factors namely

Stirring of the solution: Stirring the solution causes the solute to interact more with the solvent, thus increasing the rate of dissolution.

Surface area of the solute: The smaller the surface area of the solute, the more easier it is for it (the solute) to interact with the solvent. Hence, the smaller the surface area, the faster the rate of dissolution.

Temperature of the solvent: An increase in temperature of the solvent causes the generally causes more things to dissolve in this solvent due to increased energy of molecules in the solvent, which causes the molecules of the solute and solvent to interact more.

A decrease in the amount of solute will reduce the amount of interaction the solute (since it is in lesser quantity) have with the solvent hence the rate of dissolution will also be low (even though a solution will still be formed).

There are different factors that influences chemical equations.  The factor that causes a decrease in the rate of dissolution is decreasing the surface area of the solute.

  • Dissolution rate is simply known as the transfer rate of some specific drug molecules from the solid particles which is usually crystalline in nature into solution as self free drug molecules. The rate of Dissolution can be determined by the forces of the crystal.

Surface area is known to affect the rate of dissolution.  Note that When the total surface area of the solute particles is increased, the solute will then dissolves more quickly than ever.

The breaking of a solute into smaller pieces in turn do increases its surface area and increases its rate of solution and the act of stirring, do allows the solute to dissolve faster.
