Which of the following is not true?
- A Enthalpy change in negative for adsorption of a gas on solid.
- B Increase in temperature favours adsorption.
- C Adsorption is a surface phenomena.
- D Entropy change is negative.
Answer & Solution
Correct Answer
(B) Increase in temperature favours adsorption.
Step-by-step Solution
Detailed explanation
Adsorption is a surface phenomena that involves equillibrium between two opposing processes adsorption and desorption. \(\text { Gas }+ \text { Solid } \rightleftharpoons \text { Gas adsorbed on solid + Heat }\) As adsorption is exothermic thus according to Le-Chatelier's…
