Give one example of a chemical reaction involving homogeneous catalyst.

Explanation

### Step-by-Step Solution:

1. **Understanding Homogeneous Catalysis**:
- Homogeneous catalysis occurs when the catalyst and the reactants are in the same physical state, typically in a solution. This means they are either all in the liquid phase or all in the gas phase.

2. **Identifying a Reaction**:
- A common example of a chemical reaction that involves homogeneous catalysis is the hydrolysis of an ester.
