Which of the following is not true for the adsorption of a gas on a solid?
- A Increase in temperature favors adsorption
- B Enthalpy change is negative
- C Adsorption is more specific
- D Entropy change is negative
Answer & Solution
Correct Answer
(A) Increase in temperature favors adsorption
Step-by-step Solution
Detailed explanation
Adsorption of a gas on a solid is exothermic process as during this process condensation of gas take place. According to Le-Chatelier principle, increase in temperature favors desorption. Option (a) is not a true statement.
