Question

When dissolving a solid or liquid, as the temperature of the solvent increases, the rate of dissolution?

A. increases.
B. decreases.
C. stays the same.
D. either increases or decreases, depending upon the liquid.

Answer 1

Answer:A. Increases

Step-by-step explanation:

Heating or an increase in temperature increases the kinetic energy of particles thereby increasing their motion and how they relate and react with one another.

Increase in the temperature of the solvent is directly proportional to the rate of dissolution. The rate of dissolution increases due to the increase in kinetic energy. This makes the solvent particles interact faster with the solute particles thereby increasing the dissolution rate.
