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 :
\[\underset{{{S}^{o}}(298K){{K}^{-}}mo{{l}^{-1}}}{\mathop{\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,{{H}^{+}}_{(aq)}}}\,+\underset{-10.7}{\mathop{O{{H}^{-}}_{(aq)}}}\,\to \underset{+70}{\mathop{{{H}_{2}}{{O}_{(l)}}}}\,\] \[\Delta {{S}^{o}}(298K)=\Delta {{S}_{P}}-\Delta {{S}_{R}}\]\[=70-(-10.7+0)\] \[80.7\,J{{K}^{-1}}\,mo{{l}^{-1}}\]
