When dissolving a gas, as the temperature of a solvent increases, the rate of dissolution
a. increases.
b. decreases.
c. stays the same.
d. either increases or decreases, depending upon the liquid.

Option (A) is the correct answer.

Explanation:

When we increase the temperature of solvent then there will be increase in kinetic energy of molecules. As a result, molecules will move rapidly and thus, there will occur number of collisions between the particles.

Hence, rate of reaction will also increase that is, rate of dissolution will increase.

Thus, we can conclude that when dissolving a gas, as the temperature of a solvent increases, the rate of dissolution increases.
