Assertion : During adsorption, `DeltaG, DeltaH and DeltaS` decrease i.e., their values become negative.
Reason : Adsorption is a spontaneous process. Randomness ofr disorder decreases during adsorption.

Assertion : During adsorption, DeltaG, DeltaH and DeltaS decrease i.e., their values become negative. Reason : Adsorption is a spontaneous process. Randomness or disorder decreases during adsorption.

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

(A) For adsorption DeltaG , DeltaS , and DeltaH all have negative value. (R) Adsorption is a spontanous process accompained by decrease in randomness.

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.

Assertion : In physisorption, adsorption decreases with increase in tempetrature. Reason : Lhysisorption is of eothermic nature.

Assertion : Physical adsorption increases with increase in temperature. Reason : Physical adsorption is an endothermic process.

each question constain STATEMENT-1(Assertion ) and STATEMENT - 2 (reason). examine the statement carefully and work the correct answer accoridng to the instructions given below : STATEMEN1: For Adsorption DeltaG,DeltaH,DeltaS all have -ve values. STATEMENT-2: Adsoption is a exothermic process in which randomness decreases due to force of attraction between adsorbent and adsorbate.
