If `DeltaS_("total")` is positive the process is ..... and occurs in the ..... as mentioned. The reverse process is .......

Explanation

To solve the question, we need to analyze the implications of a positive change in total entropy (ΔS_total) in a thermodynamic process.

### Step-by-Step Solution:

1. **Understanding ΔS_total**:
- ΔS_total represents the change in entropy of the system plus the change in entropy of the surroundings. A positive ΔS_total indicates that the overall disorder or randomness of the universe is increasing.

2. **Determining the Process Type**:
...
