Here’s a explanation:
- Physisorption:
- Weak attraction (like a magnet)
- Can be reversed easily
- Happens at low temperatures
- Example: Gas sticking to charcoal
- Chemisorption:
- Strong chemical bond (like glue)
- Usually irreversible
- Happens at higher temperatures
- Example: Hydrogen sticking to platinum
Tip: Weak & easy → physisorption, Strong & sticky → chemisorption
