A) \[60.3\,\,J{{K}^{-1}}mo{{l}^{-1}}\]
B) \[80.7\,\,J{{K}^{-1}}mo{{l}^{-1}}\]
C) \[-70\,\,J{{K}^{-1}}mo{{l}^{-1}}\]
D) \[+10.7\,\,J{{K}^{-1}}mo{{l}^{-1}}\]
Correct Answer: B
Solution :
\[\Delta S={{S}_{p}}-{{S}_{R}}\] \[{{S}_{p}}=70\,\,J{{K}^{-1}}mo{{l}^{-1}}\] \[{{S}_{R}}=10.7\,\,JK\,\,mo{{l}^{-1}}\] \[\therefore \] \[\Delta S=70-(-10.7)=70+10.7\] \[=80.7\,\,J{{K}^{-1}}\,\,mo{{l}^{-1}}\]You need to login to perform this action.
