Vedclass · Answer

(B) The relationship between enthalpy change and internal energy change is given by $\Delta H = \Delta E + \Delta n_g RT$.For the reaction $N_{2(g)} + O_{2(g)} \rightleftharpoons 2NO_{(g)}$,the change in the number of moles of gaseous species is $\Delta n_g = 2 - (1 + 1) = 0$.Since $\Delta n_g = 0$,we have $\Delta H = \Delta E$.Thus,the Assertion is correct.The Reason states that all reactants and products are gases,which is true,but this alone does not guarantee $\Delta H = \Delta E$. The equality holds only because $\Delta n_g = 0$. Therefore,the Reason is not the correct explanation for the Assertion.

Assertion : $\Delta H$ and $\Delta E$ are almost same for the reaction $N_{2(g)} + O_{2(g)} \rightleftharpoons 2NO_{(g)}$.
Reason : All reactants and products are gases.
