A) \[+760.3\text{ }kJ\text{ }mo{{l}^{-1}}\]
B) \[-760.3\text{ }kJ\text{ }mo{{l}^{-1}}\]
C) \[+670.3\text{ }kJ\text{ }mo{{l}^{-1}}\]
D) \[-790.3\text{ }kJ\text{ }mo{{l}^{-1}}\]
Correct Answer: B
Solution :
[b] \[\Delta {{H}^{{}^\circ }}=\Delta {{U}^{{}^\circ }}+\Delta nRT\] \[\Delta {{H}^{{}^\circ }}=-772.7+\frac{5\times 8.314\times 298}{1000}\] \[=-760.3\text{ }kJ\,mo{{l}^{-1}}\]You need to login to perform this action.
