A) \[\Delta H=\Delta E\]
B) \[\Delta H<\Delta E\]
C) \[\Delta H>\Delta E\]
D) \[\Delta H\]is independent of physical state of reactants
Correct Answer: B
Solution :
\[CO(g)+\frac{1}{2}{{O}_{2}}(g)\xrightarrow[{}]{{}}C{{O}_{2}}(g)\] \[\Delta {{n}_{g}}=1-1.5=-0.5\] Here,\[\Delta {{n}_{g}}=-ve,\]hence\[\Delta H<\Delta E\]
