A) \[\Delta {{H}_{1}}<\Delta {{H}_{2}}\]
B) \[\Delta {{H}_{1}}+\Delta {{H}_{2}}=0\]
C) \[\Delta {{H}_{1}}>\Delta {{H}_{2}}\]
D) \[\Delta {{H}_{1}}=\Delta {{H}_{2}}\]
Correct Answer: A
Solution :
The enthalpy of \[{{H}_{2}}O\,(l)\] is less than that of\[{{H}_{2}}O\,(g)\], hence more energy will be released when \[{{H}_{2}}O\,(l)\] is formed, therefore \[\Delta {{H}_{1}}<\Delta {{H}_{2}}\].You need to login to perform this action.
