Vedclass · Answer

(D) The relationship between enthalpy change $(\Delta H)$ and internal energy change $(\Delta E)$ is given by the equation: $\Delta H = \Delta E + \Delta n_g RT$,where $\Delta n_g$ is the change in the number of moles of gaseous species. For $\Delta H 
eq \Delta E$,the condition $\Delta n_g 
eq 0$ must be satisfied. $(A)$ $\Delta n_g = 1 - 1 = 0$. $(B)$ $\Delta n_g = 2 - (1 + 1) = 0$. $(C)$ $\Delta n_g = 2 - (1 + 1) = 0$. $(D)$ $\Delta n_g = 1 - (1 + 0.5) = -0.5$. Since $\Delta n_g 
eq 0$ for option $(D)$,$\Delta H 
eq \Delta E$ for this reaction.
