A) -22.88 kJ
B) -228.88 kJ
C) +228.88 kJ
D) -343.52 kJ
Correct Answer: B
Solution :
\[57.32=\Delta {{H}_{f}}(O{{H}_{(aq)}})+\Delta {{H}_{f}}({{H}^{+}}(aq))-\Delta {{H}_{f}}\] \[({{H}_{2}}O(l)\] \[\Delta {{H}_{f}}(O{{H}_{(aq)}})=57.32+(-286.20)\] \[286.2057.32=228.88\]You need to login to perform this action.
