Which of the following is less than zero during adsorption?
A
G
B
S
C
H
D
H and 
S
Text Solution
Verified by ExpertsThe correct answer is:
D
Adsorption is process where randomness decreases and energy is released. Hence, 
S will be negative (as randomness is decreasing) and 
H will also be negative ( 
H is negative for exothermic processes).
Depending on the values of Entropy and enthalpy, the Gibbs energy can either be negative or positive.
