View answer and explanation
Correct option: B
ΔG,ΔH and Δ S\Delta \mathrm{G},\Delta \mathrm{H}\,\mathrm{and}\,\Delta \,\mathrm{S} all are negative
Option B is correct because adsorption is an exothermic process (negative ΔH\Delta H), feasible (negative ΔG\Delta G), and involves a decrease in entropy (negative ΔS\Delta S).
