The plots of the extent of adsorption (x/m) Vs pressure at different temperature are as follows;

The correct order of increasing temp for curves I, II, III, IV are ;

The correct order of increasing temp for curves I, II, III, IV are ;
Options
- A
- B
- C
- Dcan't be predicted
Correct answer
B.
Step-by-step solution
Physisorption is exothermic in nature. Therefore, in accordance with Le-Chatliers principle, it decreases with increase in temperature. This means physisorption occurs at low temperature more readily. So, The correct order of temperature for curves I, II, III, IV are :
