The correct Answer is:
To solve the question, we need to analyze both statements provided: **STATEMENT-1 (Assertion):** The physical equilibrium is not static but dynamic in nature. **STATEMENT-2 (Reason):** The physical equilibrium is a state in which two opposing processes are proceeding at the same rate. ### Step-by-step Solution: 1. **Understanding Physical Equilibrium:** - Physical equilibrium occurs when a reversible process reaches a state where the rates of the forward and reverse processes are equal. This can be seen in processes like melting and freezing, or evaporation and condensation. 2. **Analyzing STATEMENT-1:** - The assertion states that physical equilibrium is dynamic in nature. This means that even though the macroscopic properties (like concentration, pressure, etc.) remain constant, the individual molecules are still undergoing changes. For example, in a closed container of water, water molecules are continuously evaporating and condensing. 3. **Analyzing STATEMENT-2:** - The reason states that physical equilibrium is characterized by two opposing processes occurring at the same rate. This is indeed true. In physical equilibrium, the rate of the forward process (e.g., evaporation) equals the rate of the reverse process (e.g., condensation), resulting in no net change in the system. 4. **Conclusion:** - Both statements are correct. The first statement correctly describes the nature of physical equilibrium as dynamic, and the second statement accurately explains why it is dynamic by stating that opposing processes occur at the same rate. ### Final Answer: Both STATEMENT-1 and STATEMENT-2 are correct, and STATEMENT-2 is the correct explanation of STATEMENT-1. ---
