A) \[=\Delta {{U}^{o}}\]
B) \[>\Delta {{U}^{o}}\]
C) \[<\Delta {{U}^{o}}\]
D) \[=0\]
Correct Answer: C
Solution :
\[C{{H}_{4}}(g)+2{{O}_{2}}(g)\xrightarrow{{}}C{{O}_{2}}(g)+2{{H}_{2}}O(l)\] \[\Delta {{n}_{g}}=({{n}_{p}}-{{n}_{r}})=1-3=-2\] \[\Delta {{H }^{o}}=\Delta {{U}^{o}}+\Delta {{n}_{g}}RT\] \[\Delta {{H}^{o}}=-X-2RT\] or \[\Delta {{H }^{o}}<\Delta {{U}^{o}}\]You need to login to perform this action.
