The correct Answer is:
To solve the problem, we need to analyze the two statements given and determine their correctness based on our understanding of vapor pressure in solutions. ### Step-by-Step Solution: **Step 1: Analyze Statement 1** - **Statement 1**: "If a liquid solute more volatile than the solvent is added to the solvent, the vapor pressure of the solution is greater than the vapor pressure of pure solvent." - When a more volatile solute is added to a solvent, both the solute and solvent contribute to the vapor pressure of the solution. Since the solute is more volatile, it will increase the overall vapor pressure of the solution compared to that of the pure solvent. - **Conclusion**: Statement 1 is **True**. **Step 2: Analyze Statement 2** - **Statement 2**: "Vapor pressure of solution is equal to vapor pressure of solvent." - This statement implies that the addition of any solute does not affect the vapor pressure of the solvent. However, we know that when a volatile solute is added, the vapor pressure of the solution is the sum of the vapor pressures of the solute and solvent. Therefore, the vapor pressure of the solution cannot be equal to that of the pure solvent. - **Conclusion**: Statement 2 is **False**. **Step 3: Final Assessment** - Based on the analysis: - Statement 1 is **True**. - Statement 2 is **False**. - Therefore, the correct answer is that Statement 1 is correct and Statement 2 is incorrect. ### Final Answer: - **Statement 1 is True, Statement 2 is False.**
