Answer

To solve the question regarding the equilibrium of ice and water, we will analyze the statements provided and determine their validity based on the principles of chemical equilibrium.

### Step-by-Step Solution:

1. **Identify the Reaction**:
The equilibrium reaction we are considering is:
\[ \text{Ice (s)} \rightleftharpoons \text{Water (l)} \]

2. **Understanding the Effect of Temperature**:
- The forward reaction (ice melting to water) is an endothermic process, meaning it absorbs heat.
- According to Le Chatelier's Principle, if we increase the temperature, the equilibrium will shift in the direction that absorbs heat to counteract the change.
- Therefore, increasing the temperature will shift the equilibrium to the right, resulting in more water being formed from ice.

3. **Understanding the Effect of Pressure**:
- In this reaction, the solid phase (ice) has a larger volume than the liquid phase (water).
- When pressure is increased, the equilibrium will shift towards the side with a smaller volume to minimize the effect of the pressure change.
- Since the product side (water) has a smaller volume than the reactant side (ice), increasing the pressure will also shift the equilibrium to the right, favoring the formation of more water.

4. **Conclusion**:
- Both statements in the question are correct:
- A: For equilibrium ice `hArr` water on increasing temperature and pressure, more of water will form.
- R: The forward reaction is endothermic and the volume decreases on the product side.

### Final Answer:
Both the assertion (A) and the reason (R) are correct, and the reason correctly explains the assertion.
