Which one of the following characteristics is associated with adsorption?

Options

  1. A∆G∆ G is negative but ∆H∆ H and ∆S∆ S are positive
  2. B∆G,∆H∆ G, ∆ H and ∆S∆ S all are negative
  3. C∆G∆ G and ∆H∆ H are negative but ∆S∆ S is positive
  4. D∆G∆ G and ∆S∆ S are negative but ∆H∆ H is positive

Correct answer

B. ∆G,∆H∆ G, ∆ H and ∆S∆ S all are negative

Step-by-step solution

∆H<0∆ H < 0 Adsorption process is exothermic

∆G<0∆ G < 0 Adsorption process is Feasible

∆S<0∆ S < 0 Adsorption process is accompanied of decrease in entropy.
