Chapter 16, Problem 53QAP

Given the following data for sodium

Na(s): $S^{°}=51.2$ J/mol $\cdot$

K

Na(g): $S^{°}=153.6$ J/mol $\cdot$

K $\Delta H_{\text{f}}^{°}=108.7$ kJ/mol $\cdot$

K

estimate the temperature at which sodium sublimes at 1 atm.

$\text{Na}\left(s\right)\rightleftharpoons \text{Na}\left(g\right)$
