A) 0.235 kJ
B) 0.3024 kJ
C) 2.567 kJ
D) 0.0076 kJ
Correct Answer: A
Solution :
Key Idea: Use the following formula to find the value of \[\Delta E\]. \[\Delta H-\Delta E+P\Delta V\] where \[\Delta H=-0.31\,kJ\,mo{{l}^{-1}}\] \[P=1.5\,atm\] \[\Delta V=-50\,mL=-0.050\,L\] \[\Delta E=?\] \[\Delta H=\Delta E+P\Delta V\] or \[-0.31=\Delta E+(1.5\times -0.05)\] or \[-0.31=\Delta E-0.075\] or \[-0.31+0.075=\Delta E\] \[\Delta E=0.235\]You need to login to perform this action.
