Vedclass · Answer

(C) The relationship between enthalpy change $(\Delta H)$ and internal energy change $(\Delta E)$ is given by the equation: $\Delta H = \Delta E + \Delta n_{g}RT$.Depending on the value of $\Delta n_{g}$ (the change in the number of moles of gaseous species),$\Delta n_{g}RT$ can be positive,negative,or zero.If $\Delta n_{g} > 0$,then $\Delta H > \Delta E$.If $\Delta n_{g} If $\Delta n_{g} = 0$,then $\Delta H = \Delta E$.Therefore,$\Delta E$ may be lesser,greater,or equal to $\Delta H$.
