Adsorption is an exothermic process. Give reason.

Adsorption is an exothermic process. The amount of substance adsorbed should

Adsorption is an exothermic process. Explain.

Adsorption is aways exothermic.

Assertion: For Adsorption DeltaG,DeltaH,DeltaS all have -ve values. Reason: Adsorption is a exothermic process in which randomness decreases due to force of attraction between adsorbent and adsorbate.
