A) \[-312.5J{{K}^{-1}}mo{{l}^{-1}}\]
B) \[-242.8J{{K}^{-1}}mo{{l}^{-1}}\]
C) \[-108.1J{{K}^{-1}}mo{{l}^{-1}}\]
D) \[-37.6J{{K}^{-1}}mo{{l}^{-1}}\]
Correct Answer: B
Solution :
\[\Delta {{S}^{o}}={{S}^{o}}_{C{{O}_{2}}}+2\times {{S}^{o}}_{{{H}_{2}}O}-\left( {{S}^{o}}_{C{{H}_{4}}}+2\times S_{{{O}_{2}}}^{o} \right)\] \[=(213.6+2\times 69.9)(186.2+2\times 205.2)\] \[=-242.8J{{K}^{-1}}mo{{l}^{-1}}.\]You need to login to perform this action.
