Given below, catalyst and corresponding process/reaction are matched. The mismatch is

Options

A. `[RhCl(PPh_(3))_(2)]` : hydrogenation
B. `TiCl_(4)+Al(C_(2)H_(5))_(3)` : polymerization
C. `V_(2)O_(5)` : Haber-Bosch process
D. nickel : hydrogenation.

Explanation

To solve the question of identifying the mismatch between the catalyst and the corresponding process/reaction, we will analyze each option provided.

### Step-by-Step Solution:

1. **Option 1: Rhodium (Rh) with Wilkinson's Catalyst**
- Wilkinson's catalyst is represented as RhCl(PPh3)2.
- It is primarily used in hydrogenation reactions of unsaturated organic compounds.
- **Conclusion**: This match is correct.

2. **Option 2: Titanium(IV) Chloride (TiCl4) with Ziegler-Natta Catalyst**
- The Ziegler-Natta catalyst is a combination of TiCl4 and an organoaluminum compound (like Al(C2H5)3).
- It is used for the polymerization of alkenes (alpha-olefins).
- **Conclusion**: This match is also correct.

3. **Option 3: Vanadium Pentoxide (V2O5) with Haber-Bosch Process**
- Vanadium pentoxide is known to be a catalyst in the contact process, where it catalyzes the oxidation of sulfur dioxide (SO2) to sulfur trioxide (SO3).
- The Haber-Bosch process, on the other hand, is used for the synthesis of ammonia (NH3) from nitrogen (N2) and hydrogen (H2), typically using iron as a catalyst.
- **Conclusion**: This match is incorrect (mismatch).

4. **Option 4: Nickel with Hydrogenation**
- Nickel is commonly used as a catalyst in hydrogenation reactions, which involve the addition of hydrogen to unsaturated compounds to form saturated compounds.
- **Conclusion**: This match is correct.

### Final Answer:
The mismatch is in **Option 3: Vanadium Pentoxide (V2O5) with Haber-Bosch Process**. It is actually used in the contact process.
