Which of the following is correct regarding adsorption ?A. `DeltaG` is negative, but `DeltaH` and `DeltaS` are positiveB. `DeltaG` and `DeltaH` are negative, but `DeltaS` is positiveC. `DeltaG` and `DeltaS` are negative, but `DeltaH` is positiveD. `DeltaG` , `DeltaH` , and `DeltaS` are alll negative |

Answer» Correct Answer - D Adsorption generally occurs with release of energy i.e., it is exothermic in nuture. A spontanceous process like adsorption requires a negative `DeltaG` . Since the translational freedom of the adsorbae is reduced when it is adsobed, `DeltaS` is generally negative. |
