Potassium metal is a better reducing agent that sodium but still potassium metal can be obtained by reduction of potassium chloride with sodium . How does it happen ?

Explanation

To understand how potassium metal can be obtained by the reduction of potassium chloride (KCl) with sodium (Na), despite potassium being a better reducing agent than sodium, we can break down the explanation into a series of logical steps.

### Step-by-Step Solution:

1. **Understanding Reducing Agents**:
- A reducing agent is a substance that donates electrons to another substance, reducing it while itself getting oxidized. Potassium (K) is a stronger reducing agent than sodium (Na), meaning it has a greater tendency to lose electrons.

2. **Lattice Energy Consideration**:
