Question

Adsorption is accompanied with :

• A. decrease in entropy of system
• B. decrease in enthalpy
• C. the value of $T\Delta$S is negative
• D. all of the above

Answer 1

Answer: (D)

all of the above

Adsorption is accompanied with decrease in entropy and enthalpy of system. The value of T$\Delta$S is negative.

Adsorption decreases randomness and thus, $\Delta S=-ve$ and also, $T\Delta S=-ve$.
