Question

For micelle formation, which of the following statements are correct?
(A) Micelle formation is an exothermic process
(B) Micelle formation is an endothermic process
(C) The entropy change is positive
(D) The entropy change is negative

• A. A and D only
• B. A and C only
• C. B and C only
• D. B and D only

Answer 1

Answer: (C)

B and C only

Answer 2

For micelle formation, $Δ_S>0$ (hydrophobic effect).
This is possible because, the decrease in entropy due to clustering is offset by increase in entropy due to desolation of the surfactant, Also $Δ_H>0$

The Correct Option is (C): $B \;and \;C \;only$
