The correct Answer is:
To analyze the statements given in the question, we need to understand the concepts of enthalpy of formation and condensation in the context of water in its liquid and gaseous states. ### Step-by-Step Solution: 1. **Understanding Statement 1**: - Statement 1 claims that the enthalpy of formation of water in the liquid state (ΔH_f(H₂O, l)) is greater than the enthalpy of formation of water in the gaseous state (ΔH_f(H₂O, g)). - This statement is **FALSE**. The enthalpy of formation of a substance in the gaseous state is generally higher than that of the liquid state because energy is required to convert the liquid into gas (vaporization). Therefore, ΔH_f(H₂O, l) < ΔH_f(H₂O, g). 2. **Understanding Statement 2**: - Statement 2 states that the enthalpy change of condensation (ΔH_condensation) is negative. - This statement is **TRUE**. When a gas condenses into a liquid, it releases energy, which means that the enthalpy change for condensation is negative. 3. **Evaluating the Statements**: - Since Statement 1 is FALSE and Statement 2 is TRUE, we can conclude that the correct option is (d): If STATEMENT-1 is FALSE and STATEMENT-2 is TRUE. ### Final Answer: The correct option is (d): If STATEMENT-1 is FALSE and STATEMENT-2 is TRUE.
