Use the S∘ values in Appendix B in the textbook to calculate ΔS∘ at 25 ∘C for each of the following reactions. Suggest a reason for the sign of ΔS∘ in each case.
A. 2S(s)+3O2(g)→2SO3(g) (suggest a reason for the sign of S in this case)
B. SO3(g)+H2O(l)→H2SO4(aq) (suggest a reason for the sign of S in this case)
C. AgCl(s)→Ag+(aq)+Cl−(aq) (suggest a reason for the sign of S in this case)
D. NH4NO3(s)→N2O(g)+2H2O(g) (suggest a reason for the sign of S in this case)
