Question

(C) Adsorption is a spontaneous process,so the change in Gibbs free energy must be negative,i.e.,$ \Delta G < 0 $. Adsorption is an exothermic process

Vedclass · Accepted Answer

$ \Delta G < 0, \Delta S < 0, \Delta H < 0 $

Vedclass · Answer

(C) Adsorption is a spontaneous process,so the change in Gibbs free energy must be negative,i.e.,$ \Delta G Adsorption is an exothermic process,which means heat is released,so the enthalpy change is negative,i.e.,$ \Delta H As gas molecules are adsorbed on the surface of a solid,their freedom of movement decreases,leading to a decrease in entropy,i.e.,$ \Delta S According to the Gibbs-Helmholtz equation,$ \Delta G = \Delta H - T \Delta S $,for the process to be spontaneous at a given temperature,$ \Delta G $ must be negative.
