Chapter 16, Problem 50QAP

Organ pipes in unheated churches develop "tin disease," in which white tin is converted to gray tin. Given

white Sm: $\Delta H_{\text{f}}^{°}=0.00$ kJ/mol; $S^{°}=51.55$ J/mol $\cdot$

K

gray Sn: $\Delta H_{\text{f}}^{°}=-2.09$ kJ/mol; $S^{°}=44.14$ J/mol $\cdot$

K

calculate the equilibrium temperature for the transition.
