A) \[\Delta \,H\,=\,\,\Delta \,E\]
B) \[\Delta \,H\,>\,\,\Delta \,E\]
C) \[\Delta \,H\,\,<\,\,\Delta \,E\]
D) \[\Delta \,H\,\,-\,\,\Delta \,E=0\]
Correct Answer: C
Solution :
\[CO(g)+\frac{1}{2}{{O}_{2}}(g)\xrightarrow{{}}C{{o}_{2}}(g)\] \[\Delta H=\Delta E+\Delta {{n}_{g}}RT\] \[\Delta {{n}_{g}}=1-1\frac{1}{2}=-\frac{1}{2}\] \[\Rightarrow \] \[\Delta H=\Delta E-\frac{1}{2}RT\] \[\therefore \] \[\Delta H<\Delta E\]
