For the reversible process, the value of `DeltaS` is given by the expression:

Options

A. `(q_(rev))/(T)`
B. `T - q_(rev)`
C. `q_(rev) xx T`
D. `q_(rev) - T`

Explanation

To solve the question regarding the expression for the change in entropy (ΔS) for a reversible process, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Entropy**:
- Entropy (S) is a measure of the disorder or randomness of a system. According to the second law of thermodynamics, the total entropy of an isolated system can never decrease over time.

2. **Identify the Nature of the Process**:
...
