Directions: This questions consist of two statements, each printed as ...
As molarity is dependent on volume of solution and volume rises with increase in temperature. Molarity is inversely proportional to temperature. So, as temperature increases, volume increases and molarity decreases.

**Assertion (A): Molarity of a solution changes with temperature.**
**Reason (R): Molarity is dependent on volume of solution.**
The correct answer is option (b) - If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
**Explanation:**
Molarity is defined as the number of moles of solute per liter of solution. It is often used to express the concentration of a solution. The molarity of a solution can change with temperature due to two reasons:
1. Change in Volume: The volume of a solution can change with temperature. When a solution is heated, the molecules move faster and the volume of the solution increases. Similarly, when a solution is cooled, the molecules move slower and the volume of the solution decreases. As molarity is dependent on volume, any change in volume will affect the molarity of the solution.
2. Change in Solubility: The solubility of many solutes is temperature-dependent. In other words, the amount of solute that can dissolve in a given amount of solvent changes with temperature. When the solubility of a solute increases with temperature, the molarity of the solution will also increase. Conversely, when the solubility of a solute decreases with temperature, the molarity of the solution will decrease.
However, the Reason provided in the question is not a correct explanation of the Assertion. The molarity of a solution is not solely dependent on the volume of the solution. It is also dependent on the number of moles of solute present in the solution. Even if the volume of the solution remains constant, a change in the number of moles of solute will result in a change in molarity.
Therefore, while both the Assertion and Reason are correct, the Reason does not provide a correct explanation for the Assertion. The correct answer is option (b) - If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
**Reason (R): Molarity is dependent on volume of solution.**
The correct answer is option (b) - If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.

It is also dependent on the number of moles of solute present in the solution.

Therefore, while both the Assertion and Reason are correct, the Reason does not provide a correct explanation for the Assertion. The correct answer is option (b) - If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
