Question

Match the reaction (In Column I) with relation between $\Delta$H and $\Delta$E (in Column II).

Answer 1

$\Delta n_g=\sum n_p-\sum n_R$

(A) For the reaction, C(s) + $O_2$(g) $⟶$ ${CO}_2$(g), the relationship between the change in enthalpy and change in internal energy is $\Delta H=\Delta$E

(B) For the reaction, $N_2$(g) + ${3H}_2$(g) $⟶$ ${2NH}_3$(g), the relationship between the change in enthalpy and change in internal energy is $\Delta H=\Delta E-2RT$

(C) For the reaction, ${NH}_{4}HS$ $⟶$ ${NH}_3$(g) + $H_{2}S$(g)${PCl}_5$(g) $⟶$ ${PCl}_3$(g) + ${Cl}_2$(g), the relationship between the change in enthalpy and change in internal energy is $\Delta H=\Delta E+2RT$

(D) For the reaction, ${PCl}_5$(g) $⟶$ ${PCl}_3$(g) + ${Cl}_2$(g), the relationship between the change in enthalpy and change in internal energy is $\Delta H=\Delta E+RT$

(E) For the reaction, ${2SO}_2$(g) + $O_2$(g) $⟶$ ${2SO}_3$(g), the relationship between the change in enthalpy and change in internal energy is $\Delta H=\Delta E-RT$.
