A) \[\Delta E\] is always greater than \[\Delta H\]
B) \[\Delta E\] is always less than \[\Delta H\]
C) \[\Delta E\] may be lesser or greater or equal to \[\Delta H\]
D) \[\Delta E\] is always proportional to \[\Delta H\].
Correct Answer: C
Solution :
\[\Delta E\] may be greater or lesser or equal to \[\Delta H\]. \[\because \] \[\Delta H=\Delta E+P\Delta V=\Delta E+\Delta nRT\] If \[\Delta n>0\] then \[\Delta H>\Delta E\] If \[\Delta n<0\] then \[\Delta H>\Delta E\]\[\Delta H<\Delta E\] For solids and liquids \[\Delta H=\Delta E\]
