Given chemical reaction in support of the statement that all the bonds in `PCl_(5)` molecule are not equivalent.

Explanation

To demonstrate that all the bonds in the PCl₅ molecule are not equivalent, we can analyze the chemical reaction that occurs when PCl₅ is heated. Here’s a step-by-step solution:

### Step 1: Understanding PCl₅ Structure
PCl₅ (phosphorus pentachloride) has a trigonal bipyramidal structure. In this structure, there are two types of bonds:
- **Axial bonds**: These are the bonds that are aligned vertically (up and down) in the trigonal bipyramidal structure.
- **Equatorial bonds**: These are the bonds that are in the plane of the triangle, forming a horizontal arrangement.

### Step 2: Bond Stability
