The correct Answer is:
To solve the question, we need to analyze both statements provided: **Statement 1 (Assertion):** For the physical equilibrium \( H_2O (s) \iff H_2O (l) \), on increasing temperature and increasing pressure, more water will form. **Statement 2 (Reason):** Since the forward reaction is endothermic in nature and the volume of water is greater than that of the volume of ice. ### Step-by-Step Solution: 1. **Understanding the Equilibrium:** - The equilibrium in question is between solid water (ice) and liquid water. The reaction can be represented as: \[ H_2O (s) \rightleftharpoons H_2O (l) \] 2. **Effect of Temperature:** - The melting of ice into water is an endothermic process, meaning it requires heat. According to Le Chatelier's principle, if we increase the temperature, the equilibrium will shift in the direction that absorbs heat (the endothermic direction). - Therefore, increasing the temperature will favor the formation of more liquid water from ice. 3. **Effect of Pressure:** - The volume of ice is greater than the volume of liquid water. When pressure is increased, the system will respond by favoring the reaction that produces less volume. - Since the transition from ice to water results in a decrease in volume, increasing the pressure will also favor the formation of more liquid water. 4. **Conclusion on Statements:** - **Statement 1** is correct because both increasing temperature and increasing pressure lead to the formation of more water. - **Statement 2** is also correct as it correctly explains why the forward reaction is favored under these conditions (endothermic nature and volume considerations). ### Final Answer: Both statements are correct, and Statement 2 is the correct explanation for Statement 1. ---
