JEE Mains · Chemistry · STD 11 - 5. Thermodynamics and thermochemistry
The following statements relate to the adsorption of gases on a solid surfuce. Identify the incorrect statement among them
- A Enthalpy of adsorption is negative
- B Energy appears as heat
- C On adsorption, the residual forces on the surface are increased
- D Entropy of adsorption is negative
Answer & Solution
Correct Answer
(C) On adsorption, the residual forces on the surface are increased
Step-by-step Solution
Detailed explanation
Adsorption is a phenomena of attracting and retaining the molecules of a substance on the surface of a liquid or a solid resulting into a higher concentration of the molecules on the surface. After adsorption there is a decrease in the residual forces due to bond formation…
