During adsorption the `Delta H` is - ve and the magnitude of – ve value

A

goes on increasing

B

goes on decreasing

C

C remains same

D

first increase then decreases

Text Solution

Verified by Experts

The correct Answer is:
B
During adsorption the - ve value of `DeltaH` goes on decreasing because as adsorption proceeds number of adsorption sites decreases and hence exothermicity decreases.

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 : 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.
