A) \[\Delta H=\Delta E\]
B) \[\Delta H>\Delta E\]
C) \[\Delta H<\Delta E\]
D) None of these
Correct Answer: B
Solution :
\[PC{{l}_{5}}(g)\to PC{{l}_{3}}(g)+C{{l}_{2}}(g)\] For this reaction \[\Delta ng=2-1=1\] \[\Delta ng\] is positive, i.e., there is an increase in the number of gaseous moles then \[\Delta H>\Delta E\]You need to login to perform this action.
