Chapter 18, Problem 18.67SP

Use the $S^o$ values in Appendix B to calculate $\Delta S^o$ at 25o C for each of the followign reactions. Suggest a reason for the sign of $\Delta S^o$ in each case.

1. $2S(s)+3{\text{ O}}_{\text{2}}(g)\to 2S{O}_3(g)$
2. ${\text{SO}}_{\text{3}}(g)+{\text{H}}_{\text{2}}\text{O(l)}\to {\text{H}}_{\text{2}}{\text{SO}}_{\text{4}}(aq)$
3. $\text{Ag}Cl(\text{s)}\to {\text{Ag}}^{\text{+}}(aq)+C{l}^{-}(aq)$
4. ${\text{NH}}_{\text{4}}{\text{NO}}_3(s)\to {\text{N}}_{\text{2}}\text{O}(g)+2H_2\text{O}(g)$
