Question

how does free energy and entropy changes during adsorption​

Answer 1

$\fbox\pink{A}\fbox\blue{n}\fbox\purple{s}\fbox\green{w}\fbox\red{e}\fbox\orange{r}$During adsorption, enthalpy and entropy of the system are negative but ΔG must be negative so that the process is spontaneous. Adsorption is accompanied by decrease in the free energy of the system as it is a spontaneous process.

Answer 2

They change as they become negative.

• Both the system processes are negative during this phase.
• It is associated with a decline in the system's free energy since it is a spontaneous process.
• Adsorption equilibrium is reached when the gibbs reaches zero. H is negative because it is an exothermic reaction.
• Because the adherence of gas molecules to the surface diminishes unpredictability, the S is negative.
