Which of the following statements is false during adsorption of gas molecule on a metal surface?
- A Enthalpy change is positive
- B Entropy change is negative
- C Both enthalpy and entropy simultaneously decreases
- D Free energy change is negative
Answer & Solution
Correct Answer
(A) Enthalpy change is positive
Step-by-step Solution
Detailed explanation
According to the question, Adsorption is reversible in nature and is dependent on pressure as well as temperature. An increase in pressure decreases the volume of gas and thus increases the adsorption of gas molecules. Conversely, a decrease in pressure will cause the removal of…
