Vedclass · Answer

(B) For any spontaneous adsorption process,the Gibbs free energy change,$ \Delta G $,must be negative $( \Delta G Adsorption is an exothermic process,meaning heat is released,so the enthalpy change,$ \Delta H $,is negative $( \Delta H Since gas molecules are restricted to the surface upon adsorption,the randomness of the system decreases,leading to a negative entropy change,$ \Delta S < 0 $.
