Give one example of a zero order reaction.

Explanation

### Step-by-Step Solution:

1. **Understanding Zero-Order Reactions**:
- A zero-order reaction is one where the rate of the reaction is constant and does not depend on the concentration of the reactants. This means that even if the concentration of the reactants changes, the rate of the reaction remains the same.

2. **Identifying an Example**:
- A well-known example of a zero-order reaction is the reaction between hydrogen gas (H₂) and chlorine gas (Cl₂) to form hydrogen chloride (HCl):
