The correct option(s) about entropy (S) is(are)
[R= gas constant, F= Faraday constant, T= Temperature ]
For the reaction, M(s)+2H+(aq)→H2(g)+M2+(aq), if ‌

, then the entropy

[JEE Adv 2022 P2]

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,0.01M)|H+(aq,0.1M)|H2(g,1 bar )∣Pt(s)
, is an entropy driven process.
For racemization of an optically active compound, ∆S>0.
∆S>0, for [Ni(H2O)6]2++3 en →[Ni(en)3]2++6H2O (where en = ethylenediamine).
