In adsorption, the thermodynamic requirement is:
In adsorption, the thermodynamic requirement is:
Show Hint
Adsorption is generally exothermic and decreases entropy of the system.

- \(\Delta H = +ve\); \(\Delta S = +ve\)
- \(\Delta H = -ve\); \(\Delta S = -ve\)
- \(\Delta H = -ve\); \(\Delta S = +ve\)
- \(\Delta H = +ve\); \(\Delta S = -ve\)
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Adsorption is exothermic.
Adsorption releases energy, so \(\Delta H < 0\).
Step 2: Disorder decreases.
Gas molecules get immobilized on the surface, reducing randomness, so \(\Delta S < 0\).
Step 3: Final conclusion.
Hence, thermodynamic requirement is: \[ \boxed{\Delta H = -ve, \, \Delta S = -ve} \]
Adsorption releases energy, so \(\Delta H < 0\).
Step 2: Disorder decreases.
Gas molecules get immobilized on the surface, reducing randomness, so \(\Delta S < 0\).
Step 3: Final conclusion.
Hence, thermodynamic requirement is: \[ \boxed{\Delta H = -ve, \, \Delta S = -ve} \]
