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