Question:
Rate of physical adsorption increases with
Rate of physical adsorption increases with
Show Hint
Physisorption $\propto$ 1 / Temperature; Chemisorption increases with temperature initially.
Updated On: Apr 10, 2026
- decrease in surface area
- decrease in temperature
- decrease in pressure
- increase in temperature
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Exothermic Nature
Physical adsorption (physisorption) is an exothermic process.
Step 2: Le Chatelier's Principle
According to Le Chatelier's Principle, lower temperatures favor exothermic processes.
Step 3: Result
Therefore, the rate of physical adsorption increases as the temperature decreases.
Final Answer: (b)
