A) \[-\text{ }92.38\text{ }kJ\]
B) \[-\text{ }87.42\text{ }kJ\]
C) \[-97.34\text{ }kJ\]
D) \[-89.9kJ\]
Correct Answer: B
Solution :
\[\Delta H=\Delta E+P\Delta V\] \[\Delta H=\Delta E+\Delta nRT\] \[\Delta E=\Delta H-\Delta nRT\] \[=-92.38-(-2)(8.314)\times {{10}^{-3}}\times (298)\] \[\Delta E=-92.38+4.895\] \[=-87.48kJ\]You need to login to perform this action.
