A) \[60.3\,\,J{{K}^{-1}}mo{{l}^{-1}}\]
B) \[80.7\,\,J{{K}^{-1}}mo{{l}^{-1}}\]
C) \[-70.7\,\,J{{K}^{-1}}mo{{l}^{-1}}\]
D) \[+10.7\,\,J{{K}^{-1}}mo{{l}^{-1}}\]
Correct Answer: B
Solution :
Key Idea: \[\Delta S={{S}_{p}}-{{S}_{R}}\] Given, \[{{S}_{p}}=70\,J{{K}^{-1}}mo{{l}^{-1}}\] \[{{S}_{R}}=-10.7\,J{{K}^{-1}}mo{{l}^{-1}}\] \[\therefore \] \[\Delta S=70-(-10.7)\] \[=70+10.7\] \[=80.78\,J{{K}^{-1}}mo{{l}^{-1}}\]You need to login to perform this action.
