MCQ
Rate of physisorption increases with:
- ✓Decrease in temperature.
- BIncrease in temperature.
- CDecrease in pressure.
- DDecrease in surface area.
✓
Answer
Correct option: A.
Decrease in temperature.
The rate of physisorption is inversely proportional to temperature. The rate of physisorption increases with the decrease in temperature as it is an exothermic process.
