![**Elementary Reactions and Their Molecularity**
Identify each of the following elementary reactions as unimolecular, bimolecular, or termolecular, and write the rate expression.
| Reaction | Molecularity | Rate expression |
|-------------------------------------|-------------------|--------------------|
| (a) \( \text{H}_2\text{O}_2 \rightarrow \text{H}_2\text{O} + \text{O} \) | [Dropdown] | rate = [ ] |
| (b) \( \text{HCO} + \text{O}_2 \rightarrow \text{HO}_2 + \text{CO} \) | [Dropdown] | rate = [ ] |
| (c) \( \text{Br} + \text{Br} + \text{M} \rightarrow \text{Br}_2 + \text{M} \) | [Dropdown] | rate = [ ] |
**Note:**
- Unimolecular reactions involve a single molecule undergoing a reaction to form products.
- Bimolecular reactions involve two molecules colliding and reacting.
- Termolecular reactions involve three molecules colliding simultaneously, which is rare.
