Adsorption is accompanied by : also explain
A)decrease in enthalpy of the system
- B)
increase in entropy of the system
- C)
increase in free energy of the system
- D)
increase in both enthalpy and entropy
Adsorption process is always exothermic and so change in enthalpy is always negative.
It is a spontaneous process and leads to decrease in free energy.
Adsorption leads to decrease in entropy i.e. change i entropy is negative because the adsorbate molecules gets lesser opportunity to move about on the surface of adsorbent.
Therefore, option A is the correct answer.
