Which of the below best explains the relationship between the surface area of a solid solute and the dissolution (rate it dissolves) in a solvent
Question 3 options:

As the surface rate decreases the solid dissolves faster


As the surface area increases the solid dissolves faster.


As the surface area increases the solid dissolves slower.


Surface area has no affect on the dissolving rate of the solid.

Answer 1

When the total surface area of the solute particles is increased, the solute dissolves more rapidly. Breaking a solute into smaller pieces increases its surface area and increases its rate of solution. So, any answer with “as surface area increases, solid dissolves faster” would be correct. :)
