Chapter 12, Problem 21E

Calculate $\Delta S°$ for the following changes.

(a) ${\text{SnCl}}_4(l)\to {\text{SnCl}}_{\text{4}}(g)$

(b) ${\text{CS}}_2(g)\to {\text{CS}}_2(l)$

(c) $\text{Cu}(s)\to \text{Cu}(g)$

(d) ${\text{H}}_{\text{2}}\text{O}(l)\to {\text{H}}_{\text{2}}\text{O}(g)$

(e) ${\text{2H}}_{\text{2}}(g)\to {\text{O}}_{\text{2}}(g)\to {\text{2H}}_{\text{2}}\text{O}(l)$

(f) $\text{2HCl}(g)+\text{Pb}(s)\to {\text{PbCl}}_{\text{2}}(s)+{\text{H}}_{\text{2}}(g)$

(g) $\text{Zn}(s)+{\text{CuSO}}_{\text{4}}(s)\to \text{Cu}(s)+{\text{ZnSO}}_{\text{4}}(s)$
