Which statement is true for reversible process :-

Options

A. It takes place in single step
B. Driving force is much greater than opposing force
C. Work obtain is minimum
D. None

Answer

To determine which statement is true for a reversible process, we need to analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understand the Definition of Reversible Process**:
A reversible process is an idealized process that occurs in such a way that the system and surroundings can be returned to their original states without any net change. It requires the system to be in thermodynamic equilibrium at all stages.

2. **Analyze the First Statement**:
- The first option states that a reversible process takes place in a single step.
- **Evaluation**: This is **false**. A reversible process occurs through a series of infinitesimally small steps, allowing the system to remain in equilibrium throughout.

3. **Analyze the Second Statement**:
- The second option claims that the driving force is much greater than the opposing force.
- **Evaluation**: This is also **false**. In a reversible process, the opposing forces are equal to the driving forces, maintaining equilibrium.

4. **Analyze the Third Statement**:
- The third option states that the work obtained is minimum.
- **Evaluation**: This is **false** as well. In a reversible process, the work done is maximized, not minimized, because the system operates under ideal conditions.

5. **Conclusion**:
Since all the provided statements are false, we conclude that none of the statements accurately describe a reversible process.
