The correct option(s) about entropy (S) is(are) [R = gas constant, F = Faraday constant, T = Temperature] dEcell dT an entropy driven process. (C) For racemisation of an optically active compound, AS > 0. (D) AS > 0, for [Ni(HO) * +3 en R F (A) For the reaction, M(s) + 2H* (aq) H (g)+M+ (aq), if then the entropy change of the reaction is R (assume that entropy and internal energy changes are temperature independent). (B) The cell reaction, Pt(s)| H (g, 1 bar) | H+ (aq, 0.01 M) || H+ (aq, 0.1 M)| H (g, 1 bar) | Pt(s), is in [Ni(en) + + 6HO (where en = ethylenediamine).
