Equations (23) and (24) show that the molar enthalpy and the molar entropy of nanoadsorption include the bulk and interfacial phases. The effects of the diameter of the nano-adsorbent on the molar enthalpy and the molar entropy of nanoadsorption depend on the value of ð@r1P =@TÞp ð@rN=@TÞp: If the value is positive, then both the molar entropy and the molar enthalpy decreases with a
