16.3 Exercise 2

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

(a) $\text{SnCl}_{4} \left(l\right) \rightarrow \text{SnCl}_{4} \left(g\right)$

(b) $\text{CS}_{2} \left(g\right) \rightarrow \text{CS}_{2} \left(l\right)$

(c) $\text{Cu} \left(s\right) \rightarrow \text{Cu} \left(g\right)$

(d) $\text{H}_{2} \text{O} \left(l\right) \rightarrow \text{H}_{2} \text{O} \left(g\right)$

(e) $2 \text{H}_{2} \left(g\right) + \text{O}_{2} \left(g\right) \rightarrow 2 \text{H}_{2} \text{O} \left(l\right)$

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

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