The correct Answer is:
To solve the question, we need to analyze both the assertion and the reason provided. ### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states: "Ice ↔ Water, if pressure is applied water will evaporate." - When ice melts into water, it is a phase change from solid to liquid. The assertion suggests that applying pressure will cause water to evaporate. 2. **Analyzing the Effect of Pressure on Ice and Water**: - According to the principles of thermodynamics, increasing pressure generally favors the phase that has fewer moles of gas. In the case of ice melting to water, the phase change does not produce gas; hence, the assertion is misleading. - When pressure is applied, the melting point of ice decreases, which means ice will melt into water more easily. However, this does not imply that water will evaporate under pressure. 3. **Understanding the Reason**: - The reason states: "Increase of pressure pushes the equilibrium towards the side in which the number of gaseous molecules increases." - This statement is a misinterpretation of Le Chatelier's Principle. According to this principle, if pressure is increased, the equilibrium will shift towards the side with fewer moles of gas. 4. **Applying Le Chatelier’s Principle**: - In the context of water and ice, when pressure is applied, the equilibrium will favor the phase with fewer moles. Since both ice and water are in the liquid and solid states, the application of pressure does not favor evaporation (which produces gas). - Therefore, the reason is also incorrect because it does not accurately describe the behavior of the system under pressure. 5. **Conclusion**: - Both the assertion and the reason are incorrect. The assertion incorrectly states that water will evaporate under pressure, and the reason incorrectly describes the effect of pressure on equilibrium. ### Final Answer: Both the assertion and the reason are false. ---
