A: Raoult's law applicable for dilute solution only.
R: Henry's law is applicable for solution of gas in liquid.

Answer

To analyze the given statements and determine their validity, we need to break down the assertion and reason provided in the question.

### Step-by-Step Solution:

1. **Understanding the Assertion (A)**:
- The assertion states that "Raoult's law is applicable for dilute solutions only."
- **Explanation**: Raoult's law describes the vapor pressure of a solvent in a solution. It is valid for ideal solutions, which are typically dilute. In dilute solutions, the interactions between solute and solvent molecules are minimal, allowing Raoult's law to hold true.

2. **Understanding the Reason (R)**:
- The reason states that "Henry's law is applicable for solutions of gas in liquid."
- **Explanation**: Henry's law states that the amount of gas that dissolves in a liquid at a given temperature is directly proportional to the partial pressure of that gas above the liquid. This law is specifically applicable to gas-liquid solutions and is particularly relevant when dealing with low concentrations of gas in a solvent.

3. **Evaluating the Truth of Both Statements**:
- Both the assertion and reason are true statements:
- **Assertion (A)** is true because Raoult's law is indeed applicable to dilute solutions.
- **Reason (R)** is also true as Henry's law applies to gas-liquid solutions.

4. **Determining the Relationship Between A and R**:
- While both statements are true, the reason provided does not explain the assertion. Raoult's law and Henry's law describe different scenarios and are not directly related to each other. Therefore, while both statements are correct, the reason does not serve as an explanation for the assertion.

5. **Conclusion**:
- The final answer is that both the assertion and reason are correct, but the reason is not a correct explanation of the assertion.

### Final Answer:
Both assertion (A) and reason (R) are true, but R is not the correct explanation for A.
