21. Which of the following statements is correct?
(A) For HCl(g) → H+(aq) + Cl-(aq), its ∆So is larger than 0 (> 0)
(B)The So of Cgraphite(s) is larger than the So of Cdiamond(s)
(C) One mol H2 (at STP) has more positional probability than 1 mol H2 at 100 K, 0.5 atm.
(D) The sign of ∆Ssurr for the process of I2(g) → I2(s) is negative (-).
(E)At constant T and P, the change with ∆Η = +25 kJ, ∆S = +100 J/K, T = 300. K is not a spontaneous process.
