Write three distinct features of chemisorptions which are not found in physisorptions.

Explanation

To answer the question regarding the distinct features of chemisorption that are not found in physisorption, we can outline the following three features:

### Step-by-Step Solution:

1. **Nature of Bonding**:
- **Chemisorption** involves the formation of strong chemical bonds (covalent or ionic) between the adsorbate (gas molecules or atoms) and the surface of the adsorbent. This bond formation is a key characteristic of chemisorption.
- **Physisorption**, on the other hand, occurs due to weak Van der Waals forces and does not involve any strong chemical bonding.
