Which of the following is true in respect of adsorption 

Options

A. `Delta G lt O, Delta S gt O,Delta H lt O`
B. `Delta  G lt O,Delta S lt O, Delta H lt O`
C. `Delta G lt O, Delta S gt O, Delta H lt O`
D. `Delta G  lt O,Delta S lt O,Delta H gt O`

Answer

B

Explanation

In adsorption process randomness `darr DeltaS < 0` exothermic `DeltaH < 0` : spontaneous `Delta G < O`
