The correct option(s) about entropy (S) is(are)
[R = gas constant, F = Faraday constant,
T = Temperature]
[R = gas constant, F = Faraday constant,
T = Temperature]
- For the reaction, M(s) + 2H+(aq) → H2(g) + M2+(aq),
if
, then the entropy change of the reaction is R (assume that entropy and internal energy changes are temperature independent). - The cell reaction,
Pt(s)|H2(g, 1 bar) | H+(aq, 0.01 M)|| H+(aq, 0.1 M)|H2(g, 1 bar) | Pt(s), is an entropy driven process. - For racemization of an optically active
compound, DS > 0 . - DS > 0, for [Ni(H2O)6]2+ + 3en → [Ni(en)3]2+ + 6H2O
(where en = ethylenediamine).
Answer
(D) D S > 0, for [Ni(H 2 O) 6 ] 2+ + 3 en → [Ni( en ) 3 ] 2+ + 6H 2 O (where en = ethylenediamine).
