Question:

(A) Predict whether entropy increases or decreases in each of the following reactions.

(a) The Claus process for removing H2S from natural gas: 2 H2S(g) + SO2(g) → 3 S(s) + 2 H2O(g);

(b) The decomposition of mercury(II) oxide: 2 HgO(s) → 2 Hg(l) + O2(g).

(B) Predict whether entropy increases or decreases or whether the outcome is uncertain in each of the following reactions. 

(a) Zn(s) + Ag2O(s) → ZnO(s) + 2 Ag(s);

(b) The chlor-alkali process,

2 Cl(aq) + 2 HO(1) electrolysis 2 OH (aq) + H(g) + Cl(g).
