A) \[0\,J\,mo{{l}^{-1}}\,\]
B) \[2490\,J\,mo{{l}^{-1}}\,\]
C) \[-2490\,J\,mo{{l}^{-1}}\,\]
D) \[-7482\,J\,mo{{l}^{-1}}\,\]
Correct Answer: D
Solution :
\[\Delta H=\Delta U+\Delta {{n}_{g}}RT\] For the reaction \[\Delta {{n}_{g}}=12-15=-3\] \[\Delta H-\Delta U=-3\times 8.314\times 300\] \[=-7482\,J\,mo{{l}^{-1}}\]You need to login to perform this action.
