Chapter 16, Problem 14E

Consider two processes: sublimation of I₂(s) and melting of I₂(s) (Note: the latter process can occur at the same temperature but somewhat higher pressure).

$\begin{array}{l}{\text{I}}_2\left(s\right)\to {\text{I}}_2\left(g\right)\\ {\text{I}}_2\left(s\right)\to {\text{I}}_2\left(l\right)\end{array}$

Is △S positive or negative in these processes? In which of the processes will the magnitude of the entropy change be greater?
