Which one of the following characteristics is associated with adsorption?
Options
- A∆ G is negative but ∆ H and ∆ S are positive
- B∆ G , ∆ H and ∆ S all are negative
- C∆ G and ∆ H are negative but ∆ S is positive
- D∆ G and ∆ S are negative but ∆ H is positive
Correct answer
B. ∆ G , ∆ H and ∆ S all are negative
Step-by-step solution
∆ H < 0 Adsorption process is exothermic ∆ G < 0 Adsorption process is Feasible ∆ S < 0 Adsorption process is accompanied of decrease in entropy.
