A) \[1059K\]
B) \[30.5K\]
C) \[28.8\,K\]
D) \[28800\,K\]
Correct Answer: A
Solution :
\[NaCl(s)\to NaCl(l)\] Given that: \[\Delta H=30.5\,kJ\,mo{{l}^{-1}}\] \[\Delta S=28.8\,J{{K}^{-1}}mo{{l}^{-1}}=28.8\times {{10}^{-3}}kJ\,{{K}^{-1}}mo{{l}^{-1}}\] By using \[\Delta S=\frac{\Delta H}{T}=\frac{30.5}{28.8\times {{10}^{-3}}}=1059\,K.\]You need to login to perform this action.
