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.
