The correct Answer is:
To solve the question regarding the two statements about Henry's law and Raoult's law, we will analyze each statement step by step. ### Step 1: Analyze Statement 1 **Statement 1:** Henry's law is always applicable for gases. - **Explanation:** Henry's law states that at a constant temperature, the amount of gas that dissolves in a liquid is proportional to the partial pressure of that gas above the liquid. This law is indeed applicable for gases, particularly in dilute solutions. Therefore, Statement 1 is **true**. ### Step 2: Analyze Statement 2 **Statement 2:** Raoult's law is a special case of Henry's law. - **Explanation:** Raoult's law applies to the vapor pressure of components in a solution and states that the partial vapor pressure of a component in a solution is equal to the mole fraction of that component multiplied by its vapor pressure in the pure state. Raoult's law can be considered a special case of Henry's law when the Henry's constant (Kh) is equal to the vapor pressure of the pure component. Thus, Statement 2 is also **true**. ### Step 3: Determine the Relationship Between the Statements Now, we need to evaluate whether Statement 2 correctly explains Statement 1. - While both statements are true, Statement 2 does not directly explain Statement 1. Statement 1 is about the applicability of Henry's law to gases, while Statement 2 discusses the relationship between Raoult's law and Henry's law. Therefore, Statement 2 is not a correct explanation of Statement 1. ### Conclusion - **Final Answer:** Both statements are true, but Statement 2 is not correctly explaining Statement 1. ### Summary of the Answer: - The correct option is: **Both the statements are true, but statement 2 is not correctly explaining statement 1.** ---
