A) \[\Delta {{H}_{1}}>\Delta {{H}_{2}}\]
B) \[\Delta {{H}_{1}}=\Delta {{H}_{2}}\]
C) \[\Delta {{H}_{1}}<\Delta {{H}_{2}}\]
D) \[\Delta {{H}_{1}}+\Delta {{H}_{2}}=0\]
Correct Answer: C
Solution :
In the process,\[{{H}_{2}}(g)+\frac{1}{2}{{O}_{2}}(g)\xrightarrow{{}}{{H}_{2}}O(l),\]heat is evolved because state is changing from gaseous to liquid, ie, the process is exothermic. Hence, \[\Delta {{H}_{1}}<\Delta {{H}_{2}}\]You need to login to perform this action.
