If `DeltaH` is the change in enthalpy and `DeltaE` the change in internal energy for a gaseous reaction then

Options

A. `DeltaH` is always greater than `Delta E`
B. `Delta H lt Delta E` only if the number of moles of the products is greater than the number of the reactants
C. `Delta H` is always less than `Delta E`
D. `Delta H lt Delta E` only if the number of moles of the products is less than the number of moles of the reactants

Answer

D

Explanation

If `Delta n = -ve` than `Delta H lt Delta E`
