Chapter 21, Problem 6STP

To determine

To Choose: The correct option.

Answer to Problem 6STP

Option B

Explanation of Solution

With the increase in the surface area of the solvent, rate of dissolution also increases because additional surface area allows for more collisions and grinding increases the surface area of the solute and speeds up dissolving.

Conclusion:

Options (a), (c), (d) are incorrect because surface area is increased with the increase in grinding.

When surface area is increased then the speed of solute particles also increases.
